What should I pay attention to when using the automatic toluene insoluble analyzer?

What is toluene insoluble matter? What hydrocarbons are it?

Toluene insoluble ash, coal powder, graphite, and the like.

Toluene insolubles are macromolecular substances in coal tar, including dust and ash and furnace wall wear shedding, but they account for a small proportion in toluene insolubles. Coke oven operation has a great influence on its content, mainly temperature, coke oven height and coal charging mode. Coal tar post-processing temperature is the main factor affecting the increase of toluene insoluble content.

Automatic toluene insoluble analyzer performance and characteristics

4.1 The instrument is fully enclosed and designed with exhaust device, non-toxic and tasteless, safe and environmentally friendly. The isolation door is designed with tempered glass window for easy observation and safety;

4.2 Instrument counting detection adopts imported optical fiber sensor, which is sensitive to detection and sensitive work, easy to disassemble and easy to install with easy clip-on design;

4.3 The instrument adopts microcomputer chip to control automatic calculation, and the color touch LCD screen displays the number of extractions in real time. The number of extractions can be set by itself; when the experiment reaches the set number of times, an alarm sound will be emitted and the heating will be automatically turned off;

4.4 Instrument heating control is heating output power percentage (PWM) control, the adjustment mode is slider touch adjustment and display percentage, and the adjustment control is accurate;

4.5 Glass instrument 30ml, 120ml toluene reagent is added automatically by the quantitative pump microcomputer chip. After the experiment, the instrument waste liquid is automatically and quickly discharged into the closed waste liquid bottle. The whole reagent operation process does not require manual participation.
