Gas chromatography ion trap mass spectrometer

Agilent 210-MSGas chromatography ion trap mass spectrometerGC-MS is a single-stage ion trap mass spectrometer based on electron impact ionization (EI), designed specifically for routine laboratory analysis, with high sensitivity and operational flexibility. Its core performance characteristics are as follows:

1. Gas chromatography ion trap mass spectrometerIon source and ionization technology
The EI ion source using pulse ionization mode can dynamically adjust the emission current according to the sample concentration, significantly reducing ion source pollution and extending the filament life. The temperature control range of the ion source is 100 ℃~300 ℃, supporting the analysis of high boiling point compounds (inert high-temperature ion sources can reach 350 ℃). The unique Trace Ion Detection (TID) technology enhances the sensitivity and reliability of detecting trace compounds in complex matrices.

2. Gas chromatography ion trap mass spectrometerIon trap mass analyzer
Configure conventional or fully inert ion trap options, the latter suitable for high activity compound analysis. The quality range is 1.5~1050 amu, with a scanning speed of 5600 amu/s. The sensitivity to octafluoronaphthalene (OFN) in full scan mode is 1pg (signal-to-noise ratio ≥ 50:1), and the sensitivity to ion scan (SIS) can reach 100fg (signal-to-noise ratio ≥ 10:1). The ion trap adopts an all metal molybdenum quadrupole design, which has lifelong anti pollution characteristics and does not require maintenance or heating.

3. Scanning and data processing functions
Supports full scan, selective ion scan (SIS), and selective ion exclusion (SIE), the latter of which can effectively eliminate matrix interference. The built-in gain normalization tuning function ensures data comparability, coupled with retention time locked (RTL) and deconvolution reporting software (DRS), a database containing 926 compounds simplifies the qualitative and quantitative analysis of complex samples. The data processing system can automatically control chromatographic and mass spectrometry parameters, achieve mass number calibration, multiple reaction monitoring (MRM), and spectral library retrieval.

4. Gas chromatography system
Integrated 431 single channel gas chromatograph, equipped with 1177 split/non split injection ports, supporting fully inert system options and pulse pressure settings, with a maximum carrier gas flow rate of 8 mL/min (optional hydrogen to reduce costs). Capillary Flow Technology supports synchronous acquisition of multiple signals. Optional 100 bit dual inlet automatic sampler or three in one COMBI PAL automatic sampler, compatible with liquid, headspace, and solid-phase microextraction (SPME) injection.

5. Vacuum and detection system
An 80 L/s molecular turbo pump is used to maintain a high vacuum environment, and the detector is a ± 10 kV off-axis dynode electron multiplier to ensure high signal-to-noise ratio and stability. The stability of the mass axis is ≤ 0.1 amu/48 hours, and the resolution is in units of mass.

6. Application scenarios
Suitable for fields such as environmental pollutants, food safety (such as pesticide residues), petrochemicals, and forensic toxicology analysis, particularly skilled in screening and identifying trace compounds in complex matrices. Its modular design allows for upgrading from single-stage MS to multi-stage MS/MS (up to 10 levels), further expanding its structural analysis capabilities.

In summary, 210-MS, with its high sensitivity, low maintenance cost, and intelligent data processing of ion trap technology, has become an ideal choice to replace traditional quadrupole GC-MS multi detector systems.
