JEOL/Agilent JSM-Q1050GC/7890A GC/MS System Introduction

System Overview

The JEOL/Agilent JSM-Q1050GC/7890A GC/MS system represents a premium analytical instrument jointly developed by JEOL Ltd. and Agilent Technologies, combining Agilent's 7890A gas chromatograph with JEOL's Q1050GC quadrupole mass spectrometer. This modular-designed system integrates the high-efficiency separation capability of gas chromatography with the high-sensitivity detection advantages of quadrupole mass spectrometry, providing reliable solutions for environmental monitoring, food safety, pharmaceutical analysis, and other fields.

Core Technical Features

The Q1050GC mass spectrometer employs a high-precision quadrupole mass analyzer with a mass range of 10-1050 amu, resolution ≥2.5M (full mass range), and mass stability <0.1 amu/24h. The innovative hyperbolic quadrupole design combined with a digital RF power supply delivers exceptional mass spectrometry performance. The system features an electron impact ion source (EI) with adjustable ionization energy (10-200 eV) and utilizes a secondary electron multiplier (SEM) detector offering a dynamic range of 10^6. The 7890A gas chromatograph incorporates microfluidic control technology, with an oven temperature range of -80°C to 450°C, programmable heating rates of 0.1-120°C/min, and supports Retention Time Locking (RTL) functionality.

System Advantages

1. High-sensitivity detection: Detection limits reaching pg level, with signal-to-noise ratio better than 100:1 (1pg octafluoronaphthalene)
2. Excellent stability: Mass axis drift <0.1 amu/24h, retention time reproducibility RSD <0.1%
3. Intelligent operation: Equipped with MassCenter workstation supporting automatic tuning, method development, and data processing
4. Strong expandability: Optional accessories including chemical ionization source (CI), thermal desorption sampling system (TD), etc.

Typical Applications

• Environmental analysis: Detection of persistent organic pollutants (POPs) and volatile organic compounds (VOCs)
• Food safety: Analysis of pesticide residues, food additives, and flavor compounds
• Pharmaceutical research: Study of drug metabolites and impurity analysis
• Petrochemical industry: Hydrocarbon composition analysis and additive detection
