Used THERMO FINNIGAN LTQ #293829175 for sale

THERMO FINNIGAN LTQ is a spectrometer designed for use in the field of analytical chemistry. It is used to measure and analyze chemical substances, such as proteins, and to identify compounds in unknown samples. The spectrometer incorporates double focusing mass spectrometry (DFMS) which is the current standard in mass spectrometry technology. With DFMS, two independently charged electrostatic analyzers are used to isolate and measure particular ions in a sample. The FINNIGAN LTQ is a high-end instrument that has the ability to perform a variety of mass spectrometry techniques. It can be used for electrospray ionization (ESI), atmospheric pressure chemical ionization (APCI), and matrix-assisted laser desorption/ionization (MALDI). With ESI, molecules are charged and ionized by an electric field, enabling them to be transferred to the mass spectrometer's electrodes. APCI dissolves and ionizes molecules in a charged atmospheric environment, providing a soft ionization technique. MALDI combines the ultraviolet laser to create an ionization field and a matrix to quickly desorb and transfer molecules into the ionization field. The FINNIGAN THERMO FINNIGAN LTQ offers four resolution ranges, with an acquisition time of up to seven minutes. It also has an extended m/z range, accommodating larger samples. The instrument can analyze up to three samples simultaneously, allowing for running multiple samples without long waiting periods. The high speed, accuracy, and versatility of the instrument makes it ideal for applications in LC-MS or LC-MS/MS. It can also be used with HPLC systems, which provide better sample recovery and greater analytical sensitivity. The FINNIGAN LTQ has a full range of automatic features and automated processes that make operation easy and increase its measurement accuracy. Its built-in automation processes, such as sample focusing and identification, allow multiple samples to be processed quickly. The instrument also supports software interfaces with other computers, making it easier to coordinate data collection and use the spectrometer remotely. The FINNIGAN THERMO FINNIGAN LTQ is an excellent all-around choice for mass spectrometry, offering maximum versatility, sensitivity, and speed. It is a cost-effective choice for laboratory analysis and quantitative and qualitative research. With its high-performance capabilities, the FINNIGAN LTQ is an essential addition to any analytical chemistry laboratory.
