Used VARIAN AA 240FS #293749143 for sale

VARIAN AA 240FS is a fast-scanning atomic absorption spectrometer. It utilizes the simultaneous excitation of a multitude of absorbing ground state atoms in a flame or electrothermal graphite furnace to measure trace metal concentrations in various matrices. It is designed specifically for analytical laboratories utilizing the highest level of spectrometry techniques for simultaneously measuring trace metals in complex matrices. VARIAN AA240FS has a rugged sample introduction equipment comprising an automated 10-position sample changer, pneumatic moving lens optics, and an 8-position graphite furnace sample introduction. It has a wavelength range of 190-340nm and a spectral resolution of less than 0.037nm. Its optics utilize a quartz fused-silica double beam design, a pyrolytic graphite inlet system, and a 400nm high-resolution photomultiplier detector. AA 240FS features a sample changer that utilizes an automated autolab unit, allowing up to 10 samples to be loaded for simultaneous analysis. It also features an auto zero timing feature that ensures the machine is always in balance for optimal accuracy. Its automatic sample introduction tool provides rapid and repeatable sample introduction. It utilizes a pneumatic 3-lens optical path with focus optimization and high resolution optics. The double beam spectrometer configuration ensures precise, derived, and fast reading of the metals being analyzed. AA240FS also features a graphite furnace sample introduction asset. This allows for the analysis of complex samples that require higher frequency scanning for better detection. The graphite furnace sample introduction model warms the sample matrix to temperatures of up to 3000°C. This allows for the release of individual metal atoms from the sample matrix for enhanced concentrations in the final readings. VARIAN AA 240FS also features an advanced data equipment. This data system helps speed up the analysis of samples by providing a quick data processing and analysis of results. It allows the user to create databases and store reference spectra for comparison purposes. The on-board PC terminal is capable of full control and data management, including user-defined calibrations. VARIAN AA240FS offers superior performance and accuracy for all analytical applications. It enables the analysis of complex samples in multiple matrices and the exact determination of trace metals concentrations in them. This spectrometer offers excellent repeatability and provides reliable results at an affordable price.
