Scope Biodiesel free and total glycerin has a thermal conductivity detector, hydrogen flame ionization, electron capture, flame photometric, five kinds of nitrogen and phosphorus detector can be equipped with a packed column or a capillary column. The instrument can be programmed temperature thermostat operation, or third-order operation. Instrument is highly integrated, advanced design, to achieve a higher degree of automation, it can detect parameters, temperature parameters set by the keyboard implementation. Can packed column and capillary pressure and stigma real-time display, the instrument uses a single air route structure, reasonable structure, stable and reliable performance, simple operation, easy maintenance. Features 1, with power self-diagnosis function, stopwatch function (to facilitate flow measurement), running timer, power storage protection, keyboard lock and power supply with anti-interference function mutation. 2, automatic fault diagnosis: analysis end automatic exceeded prompted, provide diagnostic meet the national standard three ratios, TD shown, the component concentrations shown a variety of fault diagnostics and so on. 3, oven volume, intelligent opened the door and out of the system infinitely variable air volume, reducing the program up / cool down time after the system is stable equilibrium; furnace system :( temperature range) Ambient temperature + 6 ? ~ 400 ? .13-order program heating, heating rate of 0-50 ? / min; Increment 0.1 ? / min can recalibrate the oven temperature by the user, and arbitrarily set maximum temperature. Furnace temperature equilibrium time determined by the user. 4, all computerized key operations, large-screen LCD display, man-machine dialogue, easy to operate; Technical parameter 1. Temperature control Temperature control range: room temperature 7? -400?(incremental 0.1 degrees C) Rise order: three order Rise rate: 0.1 ? -50 ? /min (incremental 0.1 ?) 2. Detector FID Detection limit: less than 5 * 10-12g/s (sixteen -) Baseline noise: less than 6 * 10-12A/H The linear range is greater than or equal to 105 Stable time: less than 20min 3. Detector TCD Sensitivity: 10000mV = ml/mg (sixteen -) Baseline noise: less than 30uV (99.999 hydrogen carrier gas 4. FPD detector Detection limit: =5 × 10-12g / s (N) Baseline noise: =2 × 10-13A / H 5. ECD detector Detection limit: =5 × 10-12g / s (N) (r-666) Baseline noise: =2 × 10-13A / H 6. NPD detector Detection limit: =5 × 10-12g / s (N) Baseline noise: =2 × 10-13A / H
