RoHS2.0 Gas Chromatography Instrument

Model: TP100Plus-gc
Thermal cracking gas chromatography all-in-one + autosampler 3-in-1

The RoHS Directive was implemented by the European Union as early as July 1, 2006, and the revised RoHS 2.0 Directive was published in the Official Journal of the European Union in June 2015, in which four toxic and hazardous substances (DIBP, DBP, BBP, and DEHP) were selected to be included in the list of restricted substances. This revised directive will be implemented from July 22, 2019, and all kinds of restricted electrical and electronic products must meet the corresponding limit requirements in order to enter the EU market. 

The traditional chemical method has the pain points of enterprise customers, such as long time consuming pre-treatment, complicated instrument operation, high site requirements, low efficiency, high cost of post-use, and pollution.

 Therefore, manufacturers are looking for a simple, efficient, economical and environmentally friendly solution to help them implement process control and meet the requirements of the above directives. Thermal cracking gas chromatograph will be the first choice of o-benzene testing solution for manufacturing enterprises.

        The core technology of the program is thermal cracking pre-treatment (used to replace the chemical pre-treatment), the cracker will instantly heat the solid sample, the o-benzene in the solid sample is cracked into a gas, which is sent to the chromatographic column by the carrier gas, and the o-benzene mixture is separated into individual components by the column, and then enters into the hydrogen flame ionization detector (FID), and the concentration of the sample is converted into an electrical signal after gasification, which is captured by an amplifier and amplified, and is then collected and presented as a spectrogram through the chromatography workstation, and the content of the sample is calculated by the workstation through the size of peak areas of the spectrograms and the peak areas of the standard samples compared with the size of the peak areas of the standard samples.

      The first generation of thermal cracking for ROHS2.0 analysis is separated from the chromatograph, the cracker and chromatography are connected through the needle, the electrical and gas control are also separated, which results in more connecting pipelines, occupies more space, the needle is easy to be contaminated and clogged, the most important is that the contamination results in the peak attenuation, the failure is not good to be ruled out, the glass wool is easy to be miscellaneous peaks, due to the location of the quartz tube each time, resulting in quantitative reproducibility is not good, in order to effectively solve these problems, our company has specially designed this industry's first integrated thermal cracking gas chromatograph equipped with our R&D automatic sample injection system. Due to the different position of each quartz tube, the quantitative repeatability is not very good, in order to effectively solve these problems, our company specially designed this industry's first integrated thermal cracking gas chromatograph, equipped with our latest research and development of the auto-sampling system will be a good control of o-benzene risk for the enterprise to contribute to the great support.

specificities

★ HS-100AU type full-automatic program injector is the latest self-developed product of our company, which is suitable for solid sample auto-injection of cracking injector. Its originality, forward-looking, networked design concept, shape structure and sampling method, in the high-end analytical instrument industry, for our domestic instruments to catch up, dedication to the deserved scientific and technological achievements.

★ Combine the lysimeter and gas chromatograph into one. It eliminates the cumbersome gas and electrical connection lines, simplifies installation and operation, and effectively saves the experimental space. It realizes all-round operation and analysis in one machine and one station.

★ With independent patent integrated structure design, the sample injector and quartz tube has been modified to reduce the dead volume, fixed sample position, so that the sensitivity of the instrument response, repeatability indicators have improved by leaps and bounds.

   ★ Unique 30-position solid sample inlet tray. It can realize accurate positioning with the cracking heating device and chromatographic sample inlet, and can realize many functions such as program alignment, blowing samples into the cavity, blank processing, fault alarm, and so on. It can effectively save operator's time, realize unattended testing and increase working efficiency.

★ Increased pressure and flow monitoring, real-time monitoring of the carrier gas pressure and blowback flow and shunt flow changes, when a gas path leakage or blockage, the color screen display will give an alarm prompt, easy to find and solve the problem.

  ★ Due to the high boiling point of the sample, it is easy to block the blowback valve and shunt valve, we have designed a unique valve control system to prevent the sample condensation from blocking the pipeline and causing contamination. After the instrument tests the high content (more than 5000ppm) o-benzene sample, the residue is guaranteed to be no more than 1%, which will not affect the normal operation and data analysis of the next sample.

  ★ It is easy to select liquid specimen or solid specimen and the injection mode of solid sample at the control terminal.

  ★ The inlet mode for solid samples can be realized both to process all samples to be tested under the same cracking conditions and to process each sample in real time with different cracking conditions.

  ★ It can be expanded to more than 50-position sample trays as required.
