Gas Chromatography Mass Spectrometry (GC-MS)

Introduction

Gas chromatography-mass spectrometry (GC-MS) combines separation and identification of compounds. It is widely used in environmental, forensic, and pharmaceutical analysis. It solves compound identification limitations by providing both separation and molecular structure information.

Standards

ISO 6974-Natural gas-Determination of composition with defined uncertainty by gas chromatography

USP General Chapter <621>-Chromatography

European Pharmacopoeia 2.2.46-Chromatographic separation techniques

WHO TRS 1025 Annex 4-Good chromatography practices

Complies with the above standards, but is not limited to them.

Features

1. Software provides method control, calibration and reporting.

2. Data export and audit options support regulated laboratories.

3. Gas and temperature safety interlocks protect the system.

4. Stable flow and temperature control support repeatable retention times.

5. Automated sampler improves throughput and precision.

FAQ

What are the main applications of the Gas Chromatography Mass Spectrometry (GC-MS)?

The Gas Chromatography Mass Spectrometry (GC-MS) is used to separate, identify and quantify components in a mixture. It supports chemical analysis, quality control, environmental testing, food safety and pharmaceutical work requiring selective detection.

What standards does the Gas Chromatography Mass Spectrometry (GC-MS) comply with?

The instrument is designed with reference to IEC 61010 electrical safety, applicable chromatography standards and relevant GB/T methods. Columns and procedures should follow validated methods. Compliance documentation can be provided on request.

What warranty comes with the Gas Chromatography Mass Spectrometry (GC-MS)?

The system is covered for 12 months after shipment, including the main mechanism and electrical controls. Replaceable consumables and routine service items are not part of the warranty. Faults caused by improper installation outside the manual or unauthorised modification are not covered.

Will staff need special training?

No advanced specialist skills are needed for standard operation, though correct sample handling and safety practice should be followed. We supply a detailed manual and start-up support. For multi-user or regulated sites, a short staff training session can be arranged.

How long does delivery usually take?

Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.

Does the Gas Chromatography Mass Spectrometry (GC-MS) need calibration or verification?

To protect result reliability, periodic verification should be performed, typically once or twice a year. The instrument arrives factory-calibrated, and self-check routines help spot drift. We offer traceable calibration service if the site needs it.

Are consumables and spare parts easy to obtain?

Common consumables and standard spare parts are available through our service channel and are not locked to proprietary formats. Quote the model and serial number when ordering so the correct items are supplied. Lead time for standard parts is usually short.

Are options or configurations available?

The standard model can be configured with selected accessories and operating options to suit the task. Non-standard requests are assessed before quotation so the final build is clearly defined. We confirm details before production.

Is installation and commissioning included?

Most models can be commissioned by following the manual, including positioning, connections, checks and a first test run. Remote guidance is available during start-up. On-site installation, commissioning and training can be arranged separately where required.

What should be avoided when using the Gas Chromatography Mass Spectrometry (GC-MS)?

Do not use incompatible gases or solvents, block gas paths or run without carrier gas. Handle columns and detectors per their limits. Follow laboratory safety rules.
