Solvent residue tester

GC-6890 gas chromatograph is a specialized detection instrument designed specifically for the packaging and medical device industries to detect solvent residues and ethylene oxide. It is suitable for solvent residue, ethylene oxide residue, odor analysis, and solvent purity analysis in packaging, medical devices, hygiene products, related enterprises, and testing institutions.

Solvent residue testerTest Principle

Gas chromatograph is a separation and analysis tool for multi-component mixtures, which uses inert gas as the mobile phase and employs chromatographic column separation technology. When multiple analytical substances enter the chromatographic column, due to the different distribution coefficients of each component in the chromatographic column, the flow velocities of each component in the chromatographic column are different. After a certain column length, the mixed components leave the chromatographic column and enter the detector. After detection, they are converted into electrical signals and sent to the data processing workstation to complete the detection and analysis of the analyte.

Solvent residue testerTechnical Features

Switching display technology between Chinese and English, 5.7-inch LCD large screen (320 * 240). Up to 20 display interfaces, rich in information, can store 20 sets of chromatographic analysis data, and can be called at any time.

Industrial design appearance, novel and elegant, beautiful and practical, reasonable structure, and comfortable operation.

Equipped with gas cutoff protection function, it provides maximum protection for chromatographic columns, thermal conductivity cells, electron capture detectors, etc.

The eight order linear program heating function and intelligent dual rear door design truly achieve near room temperature control, with a temperature control accuracy of up to ± 0.1 ℃, meeting the requirements of wide range analysis.

Complete overheating protection and platinum resistance open circuit and short circuit alarm functions ensure that the instrument is not damaged.

Powerful self diagnostic function and Chinese fault prompts enable users to easily know the cause and location of the problem.

Adopting FLASH memory system, data protection no longer relies on batteries.

The microcomputer controlled FID detector has achieved automatic ignition function.

The high-precision stable voltage and current mode ensures precise and stable airflow. Multi channel pneumatic control system, expandable to 21 channels.

The high-performance capillary dedicated vaporization chamber realizes a true split/non split injection system.

Can install 1-4 detectors simultaneously. Can operate with dual FID, dual TCD, dual ECD, or dual NPD. TCD is equipped with dual column gas replenishment, so it can be used with single column, dual column, or capillary column.

Capable of installing and operating 1-3 sets of capillary columns simultaneously and running 3 detectors simultaneously. One instrument is equivalent to three (shared by the column chamber). Or double FID double hair. Double TCD dual hair. Dual TCD work simultaneously without affecting each other, and the carrier gas can be independent of each other. Avoiding the tedious process of replacing chromatography columns and detectors.

It can realize the series and parallel use of detectors, and perform intelligent automatic conversion through event control.

The instrument can be installed with various injection methods such as conversion furnace, thermal desorption analyzer, automatic sampler, automatic headspace sampler, and disruptor. Automatic sampling can be scheduled to achieve automatic online analysis.

The instrument is particularly suitable for various enterprises, environmental monitoring, health and epidemic prevention, universities, scientific research and other departments.
