With today's most advanced technology for the pilot, the country's first digital data processing and control phthalates United States, so the baseline noise and drift down to a new limit. Detector output digital signals directly to LC 310 workstation, avoiding the signal distortion and interference chromatography UV detector signals are generally required to bring multiple analog to digital conversion. Excellent flow cell design, significantly improves the performance of the instrument, optical system uses a precision positioning structure, high precision, small deviations, deuterium lamp and optical system using thermal isolation technology to shorten the settling time, and deuterium heat lamp to light the way affect the system to a minimum. Preamps with high impedance, low-drift instrumentation amplifier, high-resolution A / D converter. In the case of routine analysis of phthalates, the dynamic range of up to 104 to ensure the accuracy of the operands. As a result of the digital output function, the detector can be connected directly without the need for any data acquisition unit with a computer via RS232 serial port. High quality finishing and patented technology, the flow cell - in the heart of the UV detector flow cell using cone design, the signal to noise ratio compared to traditional straight hole design, improved 23.8%, thus greatly improving the sensitivity of the detector . High pressure high pressure mixer mixer design using narrow, flat piping hybrid design ideas, enabling them to increase two-phase liquid mixture of surface area contact, so as to achieve excellent mixing effect; while the mixer also has a small volume, mixing efficiency characteristics of high, in a short time so that the liquid mix phthalates testing, reducing the delay time to the maximum extent. The EU announced on 2005/84 / EC Directive in the Official Gazette December 27, 2005, the limit Phthalates content for children and other supplies. 25 Member States must in July 16, 2006 the Directive into their national legislation for by January 16, 2007 began to implement the toy phthalates, all manufacturers and importers must comply with the relevant legislation. Due to the prevalence of a large number of products currently on the PVC phthalates (Phthalates), for an effective response to the decree, phthalates (Phthalates) has been used for 40 years, it is not only used for the production of toys, but also for medical products such as catheters, intravenous tubes and sanitary gloves. However, according to a number of risk assessment results show that some phthalates (Phthalates) may be hazardous to reproductive function, sensitization, trigger asthma, even ai disease. 3P refers to three o stupid diformate: hexyl phthalate (DEHP) dibutyl phthalate (DBP) benzene ji-butyl phthalate (BBP) 6P refers containing more than three phthalic acid dimethyl stupid outside plus the following three kinds, collectively known as 6P: Diisononyl phthalate (DINP), diisodecyl phthalate (DIDP) octyl phthalate (DNOP ) phthalates 16p, detector (certified), phthalates are provided by Shenzhen Huayi Technology Co., Ltd. universal.
