Used APPLIED BIOSYSTEMS / ABI / MDS SCIEX API 4000 #9254432 for sale

APPLIED BIOSYSTEMS / ABI / MDS SCIEX API 4000 equipment is a single quadrupole mass spectrometer for liquid chromatography (LC/MS) applications. It utilizes ultraviolet and electrospray ionization (ESI) interface to allow efficient ionization of both polar and non-polar compounds. ABI API 4000 system is composed of a base unit, an ion source, an ion guide, a Quadrupole, a detector, and a data unit. The base unit holds the ion source and the Quadrupole mass filter. It provides a stable environment as well as steady source of power and appropriate pressurized carrier gas. The ion source is the first stage of the machine, where compounds are excited and ionized allowing compounds to enter the main gas stream for analysis. The ion guide is used to further ion manipulation and collision of the peaks which are ultimately sent to the Quadrupole. Its purpose is to analyze masses based on a measured base Mass Per Charge (m/z) ratio. The Quadrupole utilizes three DC voltages, a collision cell, and two radio frequency (RF) voltages that allow for separating and analyzing ions based on individual m/z. After the Quadrupole the ions move towards the detector, which is composed of an Electron Multiplier, an amplifier, and pulse height processor. The Electron multiplier boosts the electrons far beyond the limits of the amplifier allowing for the conversion of ions into electrons. The detector process the pulses and sends the information to the data tool where the output is stored for further analysis. Finally, MDS SCIEX API 4000 asset offers five different types of chromatography, two different automated sample introduction systems with cycle times ranging from 0.05 to 45 ms, and a MassWorks software package for instrument control, data analysis and drawing. APPLIED BIOSYSTEMS API 4000 is well-suited for non-targeted and targeted proteomics, drug development and metabolomics. With its proven performance, ease of use and reliability API 4000 model is a great choice for small and large-scale mass spec laboratories.
