RoHS2.0 Automatic Pyrolysis Gas Chromatography Instrument

Model: TP100Plus-gc

Pyrolysis Gas Chromatography System + Three-in-One Automatic Sampler

RoHS2.0 Compliance Solution    

The EU implemented the RoHS directive on July 1, 2006, and later issued the RoHS 2.0 revised directive in June 2015, which identified 4 hazardous substances (DIBP, DBP, BBP, DEHP) to be added to the restricted substances list. This revised directive came into effect on July 22, 2019, requiring all restricted electronic and electrical products to meet the corresponding limit requirements for entry into the EU market.

Traditional chemical methods have pain points for corporate clients, such as long pre-treatment times, complex instrument operation, high site requirements, low efficiency, high post-use costs, and environmental pollution.

Therefore, all manufacturers hope to have a simple, efficient, cost-effective, and environmentally friendly solution to help enterprises implement process control and meet the above requirements. The thermal desorption gas chromatography will be the preferred benzene testing solution for production and manufacturing companies.

Principles of Pyrolysis Solutions

The core technology of the scheme is the thermal pyrolysis pretreatment (as an alternative to chemical pretreatment). The pyrolyzer instantly heats the solid sample, converting the ortho-phenyl in the solid sample into gas through pyrolysis, which is then carried by the carrier gas into the chromatography column. The mixed components in the ortho-phenyl are separated into individual components by the chromatography column, entering the hydrogen flame ionization detector (FID). After the sample is vaporized, its concentration is converted into an electrical signal, which is captured and amplified by the amplifier and then collected by the chromatography workstation to be presented as a spectrum. The workstation calculates the sample content by comparing the peak area of the spectrum with that of the standard sample.

RoHS2.0 Thermal Desorption TP100Plus-gc

The thermal desorption used for ROHS2.0 analysis in the first generation was separate from the gas chromatograph.NeedleThe cracking instrument is connected to the chromatograph, with electrical and gas circuit controls being separate, which results in a higher number of connecting pipes and a larger space requirement.NeedleEasy to contaminate and clog, the most significant issue is the peak attenuation caused by contamination, which is difficult to troubleshoot. Glass wool can often exhibit irregular peaks. Due to the different placements of the quartz tubes each time, the reproducibility of quantification is not very good. To effectively address these problems, our company has specially designed this industry-first integrated thermal cracking gas chromatograph, equipped with our latest developed automatic sampling system, which will greatly contribute to the control of phthalate risks for enterprises.

Features

★ The HS-100AU fully automatic programmable sampler is our latest independently developed product, designed for automatic sample loading in solid sample pyrolysis injectors. Its innovative and forward-looking design concept, as well as its appearance structure and loading method, have contributed to the advancement of our domestic instruments in the high-end analytical instrument industry, offering a well-deserved scientific and technological achievement.

★ Combine the pyrolyzer with a gas chromatograph. Eliminates the complicated gas lines and electrical connections, making installation and operation simpler, and effectively saves laboratory space. Achieves comprehensive operation and analysis with one machine and one station.

★ An independently patented integrated structural design, which modifies the syringe and quartz tube, reduces dead volume, fixes the sample position, and dramatically improves the instrument's sensitivity and repeatability indicators.

★ Unique 30-position solid sample loading tray. Achieves precise positioning with pyrolysis heating equipment and chromatography injection ports, enabling programmatic movement, sample blowing into the chamber, blank treatment, fault alarms, and more functions. Effectively saves the operator's time, allows for unattended testing, and increases work efficiency.

★ Enhanced pressure and flow rate monitoring, enabling real-time surveillance of the carrier gas pressure and the changes in backflush and分流 flow rates. Should a gas line leak or clog, the color screen display will provide an alarm alert, facilitating troubleshooting and issue resolution.

★ Due to the high boiling point of the samples, they are prone to clog the back-flush and分流 valves. We have designed a unique valve control system to prevent condensation of the samples from blocking the pipes and causing contamination. After the instrument tests high concentration (greater than 5000ppm) of ortho-phenyl samples, it ensures that the residue does not exceed 1%, which will not affect the normal operation of the next sample or data analysis.

★ At the control terminal, it's convenient to select liquid standard samples, solid standard samples, or the sampling mode for solid samples.

★ The sampling mode for solid samples allows for processing all samples under the same pyrolysis conditions, while also enabling real-time processing with different pyrolysis conditions for each individual sample.

★ Can be expanded to over 50 samples as needed.
