Varian Vivta CCD Spectrometer Inductively Coupled Plasma-A

Full Description

REPAIRS REQUIRED MINOR REQUIRES A WATER CHILLER BUT PROBABLY THIS CAN BE ANY CHILLER. REPORTED THAT SOME TYPE OF SOFTWARE OR CALIBRATION UPDATE WAS NEEDED IN ORDERTO CONTINUE USING THE SPECTROMETER. BRAND NEW PARTS ​Compact, bench-mounted, simultaneous Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES) with axially viewed plasma, free running air-cooled, 40 MHz RF generator, purged echelle polychromator and a Vista Chip image-mapped Charged Coupled Device (CCD) detector, SPS3 Auto sampler and racks The entire Vista-PRO simultaneous ICP-OES is computer controlled using Varian’s ICP Expert system software. Full PC control includes all gas flows (nebulizer gas flow with optional mass flow controller), X-Y torch position (axial), ignition, RF power, safety interlocks and utilities monitoring. Varian's ICP-Expert software features many tools. Auto Max will automatically determine the optimum instrument parameters when you aspirate your sample Adaptive Integration Technology allows prominent and minor wavelengths to be measured simultaneously with the optimum integration time. Sample Nebulization and Introduction The axial sample introduction system features a glass cyclonic-action spray chamber with glass concentric nebulizer and one-piece quartz torch with an extended outer tube that excludes atmospheric gases. Torch: geometry is optimized for high precision and sensitivity at low flows and low power. It consists of a double-pass; Sturman-Masters spray chamber and v-groove nebulizer manufactured from inert, polymeric materials. Spray chamber wash-out The sample introduction system is designed for rapid washout. Four orders (10,000 x) signal washout can be achieved for most elements in less than 45 seconds. Peristaltic pump options Choose from built-in 2 or 3 channel, 10 roller peristaltic pump under full PC control including Fast Pump™ facility to improve productivity. Fast Pump operates the pump at full speed during the defined sample uptake period to improve sample throughput. The 3 channel PC controlled peristaltic pump allows for addition of reagents or internal standards. Pumped drain: The peristaltic pump automatically drains the spray chamber outlet to waste. Results Storage and Processing All results, operating conditions and sequence information for a sample batch are stored in a single worksheet file for future retrieval. Results can be reported and displayed in concentration or intensity formats. Weight and volume correction factors can be applied before or after the analysis. Full units conversion facilities are available to allow separate reporting of calibration standards in one set of units, while reporting sample results in another set of user definable units. Automatic spectral interference correction calculations are provided as standard. Signal Displays ICP Expert features powerful graphics capabilities. All spectra are viewed in real time and spectra can be scrolled through, up to 12 spectra at a time. Features graphics cursor. Spectra may be stored in both text and scalable graphics format and spectra of the same wavelength may be overlaid. Features full calibration graphics display with %RSD displayed for each point and full calibration ’goodness of fit’ table can be viewed and printed for each wavelength. A time-scan mode for optimization of multiple wavelengths with respect to time is also included. Compatible with Windows® 98/2000 network systems.
