ARCOS Inductively Coupled Plasma Emission SpectrometerMain technical features:

Spectro Analytical Instruments, a German company, is a large professional manufacturer of emission spectrometers. It has its own application technology center and spare parts bonded warehouse in Shanghai, responsible for developing instrument analysis methods according to user needs, guiding users to better utilize all functions of the instrument, and providing application training for users, so that they have no worries.
1. High optical resolution: The optical resolution of 165-340nm remains constant at 0.0085nm, and above 340nm it remains constant at 0.015nm. Whether for resolution testing, sensitivity testing, or actual sample analysis, the resolution remains constant at the above values.
2. Specially designed ultraviolet optical system: using a closed argon filled optical system combining Paschen Runge one-dimensional spectroscopy and multi CCD, it enables analysis of spectral lines below 190nm without the need for time-consuming and gas intensive chamber blowing, and can be analyzed immediately upon startup. Such as analyzing P (sensitive lines 177nm and 178nm), S (180nm and 182nm), Al (sensitive line 165nm), Pb (168nm), etc.
3. Maintenance free generator: A maintenance free generator designed with air cooling, which does not require a cooling circulating water system and is truly maintenance free.
4. Strong sample adaptability: Using a high-power solid-state generator with a frequency of 27.12MHz and a power range of 700-1700W, adjustable every 1W, the sample adaptability is *, and it can directly inject and analyze samples such as oil products and high salt solutions that require * instrument load requirements.
5. Detector without refrigeration: Due to the use of first-order spectral lines for analysis, the sensitivity is high, so there is no need to force the refrigeration detector to reduce noise to improve analysis sensitivity, and there is also no need to waste argon gas blowing the detector. Power on and start the ignition test, truly "ready to use"
6. Non overflow detector: All instruments adopt a linear detector array of about 29 blocks, each detector has an independent data processing unit, and independent analysis parameters (including integration time, etc.) can be set separately for each spectral line, without the common "overflow phenomenon" of two-dimensional detectors. Due to the independent data processing system of the detectors, the analysis time is extremely fast, and the full spectrum of the sample can be collected in 3 seconds. And it can be used in conjunction with other instruments such as HPLC (high-performance liquid chromatography), with a measurement frequency of 10 times per second.
7. Precise airflow control: The plasma gas (with a control accuracy of 0.1L/min), auxiliary gas, and atomization gas (with a control accuracy of 0.01L/min) are all controlled by mass flow computers, which can greatly ensure the stability of the instrument's test results. Generally, other manufacturers only use mass flow control for atomization gas in ICP.
8. Fully automatic control of observation height: All adopt computer-controlled precise observation height (vertical observation type) or flame and OPI interface distance (horizontal observation type). In addition, all torch tubes adopt a quick installation design, which can quickly locate the height of the torch tube and its concentricity with the coil.
9. Wide dynamic linear range: The dynamic linear range is 108.
10. True post analysis capability: During each analysis, the instrument can automatically save all spectral lines of all elements in all samples, including the standard sample. After the analysis is completed and the instrument is turned off, new elements or spectral lines can be directly added to the spectrum, and the background position or correction method of the working curve can be changed without the need for re injection analysis.
11. Complete spectral line library: In addition to providing a complete NIST standard spectral line library, it also provides recommended spectral line library, optimal spectral line library, interference spectral line library and other convenient methods for users to establish or analyze spectra. In addition, users can directly add spectral lines.
12. Observation interface: OPI ™ (Level)/SPI ™ (Vertical): OPPETRO ICP's Cold Cone Interface (OPI) ™)， Significantly improve analysis sensitivity and testing accuracy while eliminating tail flame interference, without the need for auxiliary vertical observation. SPI ™ The interface ensures that all optical paths are isolated from air interference during vertical observation, improving the sensitivity of ultraviolet spectral lines.
13. Convenient and practical automatic peak identification: It can automatically qualitatively identify any peak in the sample, bringing great convenience to the analysis of unknown samples.
