Gas Chromatography (GC)

Introduction

Gas chromatography is an analytical technique used to separate and analyze volatile compounds. It is widely used in environmental testing, food safety, and petrochemical analysis. The system provides high-resolution separation and accurate quantitative results.

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. Data export and audit options support regulated laboratories.

2. Software provides method control, calibration and reporting.

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

4. Gas and temperature safety interlocks protect the system.

5. GC, HPLC and modular configurations cover many applications.

FAQ

What are the main applications of the Gas Chromatography (GC)?

The Gas Chromatography (GC) 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.

Which standards and regulations apply to the Gas Chromatography (GC)?

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 does the warranty cover?

The complete unit carries a 12-month warranty from delivery, covering the main body, core components and controller against manufacturing defects. Consumables and wearing parts such as filters, seals and probes are not covered. Damage from misuse, improper power or unauthorised repair is excluded, and extended warranty can be quoted.

Is the Gas Chromatography (GC) difficult to operate?

The controls are designed for regular laboratory use, so most users become confident after a brief introduction. The manual walks through each step, and common settings can be saved for repeat work. Online or on-site training is available if the site requires it.

What is the typical lead time for order delivery?

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.

Is calibration included?

The unit is calibrated and tested before delivery. For ongoing accuracy, verify it against traceable reference standards every 6 to 12 months, or according to the laboratory quality schedule. We can arrange calibration service and certificates where required.

Are consumables and spare parts easy to obtain?

Filters, seals, probes and similar items are standard and can be supplied through our channel. Customers may also source equivalent items that meet the specification. Provide the model and serial number to confirm compatibility before ordering.

Are options or configurations available?

Yes, common options include different ranges, voltages, accessories, interfaces and capacity or size configurations. We confirm feasibility, specifications and any delivery impact before order confirmation. Custom requirements are reviewed case by case.

Do you provide on-site installation?

Benchtop and standard units typically require only placement and connection before use, while larger systems may need professional commissioning. We confirm the installation requirements at order stage. On-site service and training can be provided if needed.

What maintenance and safety points matter?

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.
