Optima 7000 Full Spectrum Direct Reading Inductively Coupled Plasma Optical Emission Spectrometer (PerkinElmer)

The nebulizer system in the standard configuration of the Optima 7000 is a highly corrosion-resistant configuration.

With this option, it can be coupled with instruments such as FIAS, HPLC, GC, and CE to achieve speciation analysis of elements such as arsenic, chromium, mercury, tellurium, selenium, tin, lead, copper, manganese, vanadium, platinum, nickel, and bromine. With the Optima 7000, the speciation of As, Se, and Cr can be analyzed simultaneously in a single analysis. In addition, when coupled with laser ablation (LA), it can also perform micro-zone and micro-surface analysis of coatings, hair, polycrystals, ores, and more.

Modular-design quick-detachable sample introduction system, featuring a pre-thermostatting system. Long-life, consumable-free components. Standard configuration with HF resistance. 40.68MHz free-running solid-state RF generator. Dual-view, dual-optics system, dual detectors. Fully Chinese and English bilingual software. The most adaptable HF-resistant sample introduction system. Superb high-salt and acid/alkali resistance. The nebulizer is a cross-flow nebulizer, characterized in that it does not clog during high-salt sample introduction and can directly aspirate a saturated saline solution! In addition, the nebulizer nozzle is fitted with a corrosion-resistant gemstone nozzle, giving it extremely strong resistance to HF, alkalis, aqua regia, and organic solvents! The spray chamber is made using corrosion-resistant patented Ryton technology, resistant to high concentrations of HF, alkalis, aqua regia, and organic solvents; moreover, this spray chamber has high physical strength, is not as fragile as glass spray chambers, has high sensitivity, good stability, and low memory effect. In short, the Optima 7000 sample introduction system requires no cumbersome spray chamber replacement operations and can perform analysis of 50% HCl, HNO3, H2SO4, 20% HF, and 30% NaOH; one sample introduction system is equivalent to the standard-configuration sample introduction system of other companies + one organic sample introduction system + one HF-resistant sample introduction system + one high-salt-resistant sample introduction system. The simplest design achieves the easiest maintenance. The dual-door design ICP sample introduction system not only makes the spray chamber and plasma torch easy to detach, but also allows adjustment while the plasma is ignited and operating; at the same time, the RF radiation shielding of the RF generator is the most comprehensive, with RF radiation leakage being the smallest in the industry. The snap-latch design makes detachment very convenient, allowing the sample introduction center tube to be detached, cleaned, or replaced without removing the sample compartment. The dual-door design also isolates the effect of high plasma temperature on the nebulizer and spray chamber temperature, improving instrument stability. The integrated sample introduction system and bayonet design make detachment of the sample introduction system extremely convenient—it can be completed by hand in 1 minute without any special tools. The Optima 7000's sample introduction system has a short channel, thus greatly reducing the time for the sample to flow through the tubing; the software features the patented Smart Rinse function, which intelligently determines the rinse time between samples. The most outstanding performance. The detection limits provided by PerkinElmer to users are all data obtained with the HF-resistant gemstone nozzle cross-flow nebulizer and the HF-resistant Ryton material Scott spray chamber of the instrument's standard configuration; if the user's sample absolutely does not contain HF acid and high salt content, a concentric nebulizer and cyclonic spray chamber can also be selected, and the detection limits can be further improved. The most advanced RF generator—solid-state RF generator. The newly designed 40.68MHz free-running generator adopts a new-generation solid-state circuit technology; the entire generator body is merely a highly integrated circuit board, with no heat-generating components such as power tubes; the service life of components is more than 10 times that of power tubes, with strong reliability, good stability, and high energy coupling efficiency; the instrument volume is also greatly reduced, making the Optima series ICP-OES a compact benchtop instrument. RF generator with 40.68MHz excitation frequency. As is well known, as the frequency increases, the energy generated by the oscillator can be transferred more effectively to the plasma, greatly improving transfer efficiency, making ignition easier, and allowing the use of low power to reduce background noise and extend the life of the generator. At the same time, the plasma has better adaptability to samples and will not extinguish when the sample changes. In addition, because the central channel becomes wider, a large-bore sample introduction tube can be used, so that high-salt samples do not clog. Therefore, using a 40.68MHz excitation frequency is far superior to 27.12MHz. The 40MHz free-running high-frequency generator designed and produced by PerkinElmer itself is fully designed according to the specific requirements of the instrument and is perfectly integrated with the instrument to achieve the best performance. Mismatches caused by products from different manufacturers are completely avoided. Free-running RF generator. The free-running generator has a simple structure, fast matching speed, high transfer efficiency, and a more stable working state, avoiding the instability and extinguishing phenomena of crystal-controlled separately-excited generators caused by slow response speed. The Optima series ICP-OES also applies the patented True Power Control technology (TPC), using real-time power monitoring and feedback technology to overcome drift and instability caused by external voltage changes, realizing continuously adjustable power in 1W increments, which can meet the needs of different analyses and is far superior to other manufacturers with large step-change power. The most comprehensive control. PerkinElmer's electronic engineers adopted a brand-new electronic control technology in the system, using multiple CPUs to independently control each part of the instrument. Large-scale integrated circuits and modular design make the instrument failure rate extremely low. The Optima series ICP-OES is the only truly full-featured, fully automatically controlled ICP spectrometer; the entire instrument has only one power switch, and all other very sophisticated functions are fully automatically controlled by computer. The most successful dual-view ICP-OES. Advantages and disadvantages of side-on view and axial view. As is well known, the detection limit using axial view can be improved by up to 10 times compared with side-on view. In the presence of a large amount of matrix, the detection limits of the vast majority of elements will be significantly improved, which is very advantageous for the analysis of trace elements; for example, when determining trace harmful elements such as As and Sb in steel, axial view fully demonstrates its superiority. However, because the light intensity increases by orders of magnitude during axial view, if there is only axial view, then when measuring high-content elements one can only select sub-sensitive lines, but this is often limited; for example, when Na content is high, the 589.583nm spectral line intensity is too high, while its 330nm spectral line is strongly interfered with by Zn, so side-on view is more suitable when analyzing high-content elements. The shortcoming of traditional vertical-view ICP-OES is that different observation positions need to be optimized when determining different elements. DualView (DV)—the most successful dual view. The Optima 7000 adopts patented dual-view technology, allowing users to simultaneously obtain the advantages of both observation modes in a single analysis; whether axial view or side-on view, the observation position is fully automatically optimized by computer, and there is a concise and practical air-cutting technology to eliminate the tail flame; in addition, an attenuator is added in the optical path, which can automatically perform four selections—axial/side-on, full-light/attenuated—not only improving sensitivity but also expanding the linear range, greatly increasing the flexibility of analysis and improving analytical performance. PerkinElmer's dual-view design and the analytical results of the 304L B.S. 81G stainless steel standard. Here, analyzing Mo and Nb requires the use of an HF-resistant sample introduction system; analyzing low-content B requires the axial view mode, while high-content Cr requires the radial attenuated observation mode. Flexible and easy-to-use fully Chinese highly intelligent operating software. Simple, easy-to-use, and powerful Chinese software. Based on the Windows?XP WinLab 32 operating system, powerful functions, supporting true multitasking and multi-user operation; raw data is non-overwritable, and all legal modifications made to raw data are recorded; when issuing inspection reports, its data has legality and traceability, meeting regulatory requirements and international certification conventions. The software has simulated operation and offline operation functions, especially suitable for teaching and data analysis. The operation of the instrument is fully automated, including observation direction and height selection, gas flow control, RF power adjustment, fault diagnosis, etc. Automatic adjustment of integration time: before each measurement, a reasonable analysis time is automatically selected according to the signal intensity obtained from pre-exposure, and the integration time can be as short as 1ms. The industry's most comprehensive 50,000 spectral line library and the software's qualitative and semi-quantitative functions greatly enhance the ability to analyze unknown samples. It has the capability of simultaneous background subtraction; for complex samples, the convenient, effective, and reliable spectral line interference subtraction function MSF can also be used. Patented spectral line resolution function—Multi-Spectral Fitting technology (MSF). PerkinElmer's unique spectral interference subtraction function solves the problem of spectral line interference in the analysis of complex matrix samples by ICP-OES. Its principle is to use modern chemometrics and multiple linear regression algorithms to separate the analytical spectral line from the interfering spectrum through a mathematical model when analyzing complex matrix samples. Since only the peak shape needs to be kept stable, the model is usually independent of sample concentration and specific ionic conditions, so it is very convenient in practical application—simply aspirate the blank solution, the analyte element solution, and the interfering element solution. This method not only has a remarkable effect on spectral interference subtraction, but can also improve the signal-to-noise ratio and further improve the detection limit. Advanced options for expanding instrument functions. High-precision mass flow controller option. The nebulizer gas of the sample introduction system is controlled by a high-precision mass flow controller that is more advanced than a rotameter, which not only improves precision but also allows automatic adjustment of any flow rate, with a minimum step of 0.01 L/min, so that the working conditions for different samples can all be optimized. Speciation analysis option, micro-area analysis option. Rapid automatic analysis option. It can accommodate up to 1260 sample positions and analyze more than 500 samples per hour; during ICP-OES reading analysis, the autosampler takes the next sample, shortening the reading delay time to 1 second. Sample consumption is 0.1 mL.
