JMS-TQ4000GC Triple-Quad Mass Spectrometer

Description

The JMS-TQ4000GC is a triple quadrupole mass spectrometer configured for gas chromatography. It is designed for quantitative analysis of target compounds at trace levels, with applications including pesticide residues in agricultural materials, regulated chemicals in water, and persistent pollutants like dioxins and PCBs. The mass analyzer is a triple quadrupole system with a mass range from 4 to 1022. It features a short collision cell intended to enhance sensitivity and reduce acquisition times. A noted specification is a Selected Reaction Monitoring (SRM) switching speed of 1,000 channels per second, which allows for the rapid analysis of multiple compounds. The system utilizes pulsed ion ejection designed to minimize crosstalk between SRM channels. Ionization sources available are electron ionization (EI) as standard, with optional chemical ionization (CI) and photoionization (PI). The scanning speed is listed as 22.222 u/s. The instrument also supports direct insertion and direct exposure probes for alternative sample introduction. Associated software provides tools for data analysis and report generation.
