Used VAREX ELSD II A #109820 for sale

VAREX ELSD II A is a highly advanced lab equipment and accessory, designed to facilitate the study of liquid or gaseous organic molecules. The device is composed of two main components; a vacuum equipment and an electron spray ionization (ESI) source. The vacuum system enables the study of organic molecules in their native state, free from any contamination. The ESI source is based on the principle of electrostatic deflection of ions from the electrodes and functions by passing a current of argon gas through a heated filament. The resulting plasma forms a highly charged ionized gas, which allows for the study of organic molecules free from any environmental contamination. ELSD II A also utilizes a sensitivity enhancing technology called differential two-dimensional recoil inlet (D2RI). This technology involves two sets of perpendicular electrodes to generate an alternating electric field. This field strength is adjustable, allowing the researcher to determine the optimal ionization condition. Through careful adjustment of the field, researchers can maximize the ionization efficiency of the sample and obtain highly sensitive data. The device further features an array of detectors, including dual photomultiplier detectors imbedded inside the ESI source, a two-dimensional detector (2DD) in the Recoil Inlet, and a quadrupole analyzer at the vacuum source as a part of its analytical unit. These detectors are used for controlling the ionization conditions and for the detection and identification of compounds present in the sample. Furthermore, VAREX ELSD II A also offers an array of accessory options including an integrated pulse gas chromatography (GPC) machine, a sampling tool, and an optional monostatic optical detector (MID). These accessories allow researchers to study the components of samples in greater detail. Overall, ELSD II A is a highly advanced lab equipment and accessory ideal for studying liquid or gaseous organic molecules. Its high sensitivity and its ability to perform a variety of measurements allows for deep exploration of organic molecules and for greater understanding of their properties.
