Used THERMO FINNIGAN LCQ #9258907 for sale

THERMO FINNIGAN LCQ is a type of mass spectrometer that is used for analyzing complex biological mixtures. It is a type of liquid chromatography-mass spectrometry (LC/MS) that combines chromatographic separation techniques with mass spectrometry to identify and quantify chemical components of a sample. A typical instrument consists of a LC pump, an ion source, an ion guide, a mass analyzer, and a detector. LCQ is capable of providing high-resolution data and accelerating the speed of sample analysis. THERMO FINNIGAN LCQ equipment utilizes a technique called liquid chromatography for separating and analyzing complex samples. In this method, a sample is first injected into a column and subsequent separations are obtained by passing a mobile phase fluid that contains constituents of interest through the column. The separated components then enter a detector and are measured based on their retention time and intensity of response. LCQ is typically used to analyze a variety of samples including, but not limited to, proteins, nucleic acids, and metabolites. When analyzing proteins, the sample is first digested with a protease, such as trypsin, before being injected into THERMO FINNIGAN LCQ system with an appropriate matrix. This proteases cleaves the proteins into peptides, which are further separated by the mobile phase. The ion source of LCQ is capable of producing a variety of charged species, resulting in the formation of ions from the sample components. The ions are then transferred to the mass analyzer, where they are separated according to their mass-to-charge ratio. Finally, the ions pass through the detector for detection and quantitation of components in the sample. THERMO FINNIGAN LCQ unit is highly efficient and provides precise data. It is mainly used in the pharmaceutical industry for analysis of small molecules as well as biotherapeutics, in the food industry for identification of distinct food components, and in proteomics for protein characterization. LCQ is also used by military and law enforcement for drug testing. THERMO FINNIGAN LCQ machine is a robust and efficient tool for complex sample analysis, providing specific and reliable data. It can be used to identify and quantify thousands of components in a single injection and is capable of analyzing complex biological mixtures.
