ASTM D6584 Free Glycerol and Total Glycerin in Biodiesel Tester

Free Glycerol and Total Glycerin in Biodiesel Tester ASTM D6584

Product Model: JF6584

Product Introduction

The content of free glycerin and total glycerin reflects the quality of biodiesel, due to the separation of glycerin, too high content of free glycerin may cause some problems during storage or in the fuel system, and too high content of total glycerin can cause injectors fouling, and deposits can form on injector nozzles, pistons, and valves. The instrument is the first of its kind in China. It is calibrated using two sets of domestic standards and 4 reference materials. By comparing with the standard specifications of monoolein, diolein and triolein, the measurement of monoglyceride is carried out respectively. Determination of lipids, diglycerides and triglycerides. The usual conversion factors are applied to mono-, di-, and triglycerides to calculate the amount of bound glycerol in the sample.

Main Feature

1. Comes with a two-way valve control system to facilitate online automatic sampling;

2. The column defense circuit enables the guidance during the program wake-up operation to obtain electronic certification, which reduces the complexity caused by the second column, detector and auxiliary flow system;

3. The signal output of the detector signal, the transmitted flow rate, the temperature of the heating furnace, the columnar output read or stored by the sensor can be connected to an analog output channel, which can be performed independently at the same time;

4. Self-test and fault diagnosis, power-off protection test data, stopwatch and functional modules, keyboard lock function;

5. It can be connected to an anti-control workstation to realize real-time control, and can save 100 sets of experimental conditions and spectra;

6. Two flow sensing channels can be installed, two single-column guaranteed channels;
