Gas Chromatograph

Features

• The new "dual-core" processor is adopted to further improve the control accuracy of the electronic gas circuit to 0.001psi;
• The new material of the heating wire with outer coating insulation function can effectively prevent the oxidation and aging process of the heating wire, ensuring the lasting stability of the heating efficiency and the long-term working life of the vulnerable parts;
• The full touch screen operation is more streamlined and more modern;
• The new software operating system that complies with the laboratory standard certification GLP/FDA-21CFR Part11 makes laboratory management more effective and data more secure;
• The adaptation of the mass spectrometer detector (MSD) makes the detection more comprehensive and reliable;
• The upgraded software Chemlab 2.0 project management, audit tracking and other functions make the analysis results complete and reliable
• The three-dimensional guide rail type fully automatic sample processing/injection system integrates functional modules such as liquid automatic injection, sample automatic dilution, headspace injection, solid phase microextraction pretreatment injection, etc., which not only improves the batch effectiveness and repeatability of laboratory analysis work, but also enriches the processing methods and means for various complex samples.

Typical Application

1. TVOC detection (GC-FID method)

2. 35 VOCs in ambient air (GC-MS method)

3. Refinery gas analysis (GC-FID, TCD method)

Accessories

Auto Sampler

It is a three-dimensional rail-type liquid automatic sampler, with 152 sample processing positions, suitable for high-throughput processing of large quantities of samples. It is an indispensable assistant for your laboratory.

Main features of Auto Sampler:

• Optional fast and slow injection
• Sampling speed is adjustable in 7 gears (suitable for samples with high viscosity)

Applications

NMTH analysis solutions
1. NMTH analysis solutions	According to the HJ 604 and HJ 38 standards of the Ministry of Environmental Protection, a unique built-in self-priming sampling system, dual-channel single-FID detection, and post-run automatic reverse pipeline cleaning are adopted for the instrument, which is suitable for the determination of NMTHs in ambient air and waste gas from stationary pollution sources.
2. VOC analysis solutions	According to HJ 759 of the Ministry of Environmental Protection and related standards, 116 volatile organic compounds in the ambient air are determined using the atmospheric pre concentration system for injection, double columns and heart cutting, and FID and MS dual channels for detection. This solution can achieve perfect cutting of low carbon components without oven cooling.
Food safety
1. Multi-residue analysis solutions for pesticides in vegetables and fruits	According to NY/T761 of the Ministry of Agriculture and related standards, the dual-tower liquid autosampler is used for sample injection, and FPD and ECD dual-column dual-channel detection is used to de t e rmine the multipl e r e s idue s of organochlorine and organophosphorus pesticides in vegetables and fruits, which is an efficient solution to truly realize multiple purposes with a single instrument.
2. Multiple pesticide residue analysis solutions for food	According to GB 23200.113, a triple quadrupole tandem mass spectrometer is used to analyze 208 pesticide residues and their metabolites in plant-derived foods. Ultra-deactivated flow paths, especially injection ports with ultra-deactivated surface treatment, keep chromatographic peaks of highly active organophosphorus pesticides still sharp and sensitive, and greatly reduce matrix effects of samples.
