Used FINNIGAN DSQ II #9108846 for sale

FINNIGAN DSQ II is a mass spectrometer, generally referred to as an "quadrupole" spectrometer. This type of spectrometer is used to measure the mass of molecules and atoms in a sample and can be used to analyze a wide range of molecules. DSQ II is commonly used in analytical chemistry laboratories, as it offers fast and accurate measurements with a minimum of sample preparation. FINNIGAN DSQ II consists of four main components: the ion source, the quadrupole mass filter, the electron multiplier, and the computer equipment. The ion source is where the sample is excited to release ions which can then be sorted according to their mass and charge. The quadrupole mass filter is used to select the desired ions by their mass-to-charge ratio (m/z) and direct them to the electron multiplier. The electron multiplier is a device that amplifies the electrical signal of the ions and amplifies it for further analysis. Finally, the computer system is used to analyze and store the data. DSQ II has a wide range of mass range, from 1 mass unit (amu) to 40,000+ amu, and a scan speed of up to 500 spectra per second. This allows it to rapidly analyze samples with minimal sample preparation or manipulation. The unit is also highly sensitive, with a mass resolution of 0.3 to 3,000 amu. FINNIGAN DSQ II is equipped with a variety of data acquisition modes, including scans, SIM, and selected-ion monitoring, which allow users to acquire a wide range of data. DSQ II is powered by a high-performance vacuum machine and advanced temperature controllers, allowing it to handle highly volatile samples. The unit is also highly reliable and easy to maintain, with fewer points of failure and maintenance taking only a few minutes. FINNIGAN DSQ II can also be interfaced with other analytical instruments, making it ideal for interfaced systems used in research laboratories. In summary, DSQ II is a modern, fast, reliable, and highly sensitive mass spectrometer. Its high mass range, scan speed, and advanced capabilities make it ideal for analyzing a wide range of molecules and atoms. With its easy maintenance and advanced user interfaces, this spectrometer is a great choice for laboratories requiring fast and accurate data.
