Water bath nitrogen blowing instrument operation process and precautions

JTONE

The series nitrogen blower is an intelligent digital display instrument independently developed by our company. The nitrogen blowing concentration heating device is suitable for sample preparation in liquid phase, gas phase and mass spectrometry. It uses an internationally recognized method to blow nitrogen into the surface of the heated sample for sample concentration. It is time-saving, easy to operate, easy to control, and can quickly achieve the expected results. The solid phase extraction pretreatment technology replaces the traditional liquid extraction and chromatography technology, which can quickly separate and purify the sample. The use of nitrogen blowing heating instead of the common rotary evaporator for concentration can greatly shorten the analysis time. Widely used in pharmaceutical, medical testing, pesticide residues,

The best matching equipment for solid phase extraction equipment. Widely used in chemical, pharmaceutical, public security, environmental and other fields. With its beautiful appearance, practical and inexpensive, it is well received by users.

JTONE

Series nitrogen concentrating device, in order to meet the different needs of users, the heating mode is divided into dry aluminum block heating and water bath heating. The former has a fast heating speed, is clean and convenient, and can be used as a thermostat for other experiments; The heat is gentle and can also be used as a constant temperature water bath in other experiments.

Connect the air pipe to the air inlet of the purge head.

Turn on the power and set the temperature control table

Water bath nitrogen blowing instrument operation process and precautions

1.

After the instrument is installed, plug in the power plug on the main unit and turn on the power switch.

2.

Connecting a nitrogen line to the gas distribution chamber interface;

3.

Arrange the position of the air needle channel used in advance (the unused channel should be closed)

4.

Set the temperature (water bath nitrogen must first add water to the sink, the water level is the sink

1/3

To

2/3

Height), after the temperature is stable, put the sample tube into the hole of the heating block (or test tube rack);

5.

Adjusting the height of the gas chamber, and the position of the interface between the gas outlet and the sample;

6.

Slowly open the nitrogen main valve (to prevent sample splashes, causing loss and contamination) and observe the purge condition, fine-tune the gas needle height position and valve flow until the sample surface is corrugated.

Precautions:

1.

Water bath heating must first add water and then energize to prevent burning of the heating body;

2.

Turn off the power supply and nitrogen bottle in time to avoid unnecessary loss and waste.
