Used SHIMADZU QP 5000 #127383 for sale

SHIMADZU QP 5000 is a double-focusing, quadrupole mass spectrometer used to accurately measure the mass-to-charge ratios of ions. QP 5000 consists of four main components - the ion source, quadrupole filter, reflectron and detector. The ion source is used to generate charged particles from a sample, which can take the form of a solid, liquid or gas. During this process, the sample is introduced into the ion source where the sample is heated and ionized. This can occur through the use of electron impact, chemical ionization or thermal desorption. The ionized particles are then accelerated into the vacuum environment of the mass spectrometer. The main component of the spectrometer is a set of four parallel rods forming a quadrupole filter. This component contains an alternating electrical field that allows ions to pass through depending on their mass-to-charge ratio. This allows only certain ions to pass through the quadrupole filter, which is then directed to the reflectron for further separation. The reflectron is a device that amplifies the mass/charge differences of the sample, enabling more precise and accurate readings. The reflectron is positioned at the end of the vacuum chamber, where the ions hit a metal plate and are reflected onto a detector. The detector is used to collect the data, which is displayed in a graph known as a mass spectrum. This graph can be used to identify the ions present in the sample and measure their mass-to-charge ratios. SHIMADZU QP 5000 provides excellent accuracy and sensitivity for analyzing complex samples, due to its use of a double focusing system and quadrupole filter. This allows for the precise and accurate measurement of the mass-to-charge ratios of ions, enabling the user to get reliable and reproducible results every time.
