Used VARIAN 1200 #293811370 for sale

VARIAN 1200 is a double-focusing magnetic sector field mass spectrometer, designed to provide high performance and high resolution in the analysis of gas and liquid samples. The instrument is capable of measuring masses from 0.1 to 1200 amu. It is equipped with an electrospray ionization (ESI) source, a diode array detector, and an auto-tuning ion extraction equipment for optimal performance. VARIAN 1200 features a double-focusing system, which enables it to adjust the magnetic and electric fields to attain the highest mass resolution and sensitivity. The unit is composed of two concentric electrostatic sectors, and each sector can be independently adjusted to provide an optimal field for each type of sample. The instrument is also equipped with an ESI source and an ion extractor. The source is operated in negative or positive mode, and delivers ions directly to the mass analyzer. The ion extractor contains an array of gradient lenses and draws positive ions into the pathway of the mass analyzer for analysis. 1200 is equipped with a diode array detector, which is used to detect ions as they traverse the mass analyzer. The detector consists of two parts - an array of light-emitting photodiodes and an array of photo-detectors - and both components are used to measure the mass-to-charge ratio (m/z) and abundance of ions. VARIAN 1200 is an extremely versatile instrument, and it is capable of providing low levels of detection and high levels of accuracy. Its double-focusing design enables it to address diverse types of samples, and the inclusion of the autotuning ion extractor machine minimizes time spent on sample preparation. For these reasons, 1200 is an excellent tool for a variety of analysis applications.
