Instrument Introduction

The GC2030 headspace gas chromatograph is a gas chromatograph configuration scheme provided by Tate Instruments based on relevant detection standards for substances that require headspace injection method detection. It is based on the GC2030PLUS gas chromatograph platform and is equipped with a dedicated headspace sampler (semi-automatic headspace and fully automatic headspace models can be selected). It can be used for residual headspace gas chromatography of epoxyethane and epichlorohydrin in medical devices, headspace gas chromatography of gas content in transformer insulation oilHeadspace gas chromatography for ethanol content in blood, headspace gas chromatography for methanol and acetone in environmental water quality, volatile aromatic hydrocarbons in soilDetection standards for headspace gas chromatography, testing of volatile halogenated hydrocarbons in water quality, headspace gas chromatography for solvent residue, and other detection methods

Various testing standards related to headspace gas chromatography, such as

Instrument characteristics

1. The headspace gas chromatography configuration scheme is suitable for the detection of various volatile substances using headspace gas chromatography. There are semi-automatic and fully automatic headspace samplers to choose from, with simple operation and easy maintenance.

1. New production process, redesigned the air supply path and internal structure inside the instrument, more reasonable component layout, reduced component signal interference, improved detection accuracy, and excellent stability and durability of the equipment.

2Adopting a 7-inch color touch screen control and a professional chromatograph UI operation interface design, it intuitively reflects the internal temperature values of the injection port, column temperature box, and detector, as well as the values of each detector, and the running time. It has a one click cooling function, and users can set their own detection conditions, making it very convenient to use.

3. Using an electronic gas path control system instead of a mechanical pressure reducing valve, the system program precisely controls the pressure and flow rate of the hydrogen loaded air three gases through an electronic gas path control unit (EPC/AFC), improving the repeatability of the equipment. Under the experimental conditions of using an automatic sampler for injection, the repeatability error of instrument testing can reach 1.5%, which is better than the 3% specified in the national standard.

4. The column temperature box adopts a six channel independent temperature control system, an automatic rear door opening system, a 21 stage 21 platform program temperature rise, fast temperature rise/fall speed, and a temperature control accuracy of 0.1 ℃, making the equipment capable of large-scale sample analysis.

5. The whole machine adopts modular design and can work in parallel with multiple processors. It includes 2 types of injection port modules (capillary column injection port and packed column injection port), 5 types of high-performance detector modules (FID, TCD, ECD, FPD, and NPD), and can install multiple injection ports and detector modules according to customer requirements (customizable six way valve, ten way valve gas injector, top air injector, thermal analysis injector, cracking furnace injector, methane conversion furnace). It supports up to 3 sets of injection ports and 4 types of detectors, making it convenient for users to upgrade and modify in the later stage.

6. It can be directly connected to the computer and operated through the PC network version chromatography workstation software (with a maximum support of 253 units) to achieve program control of the instrument's injection port, column temperature box, and detector temperature rise and fall. Under the condition that the customer is equipped with an automatic injection valve (or automatic sampler), it is possible to achieve a series of testing processes such as unmanned instrument operation, automatic temperature rise and ignition of the instrument, automatic loading method, and automatic calculation of test results, meeting the requirements of online testing.

7. The Internet of Things chromatograph technology, with built-in IP protocol stack, can upload test data to the computer of the on-site laboratory, department heads and superior leaders through the corporate LAN or the Internet, so that each department can monitor the operation of the instrument and test results in real time. It can directly connect with the manufacturer through the Internet to realize remote diagnosis of gas chromatograph, remote program update, etc.
