12 square water nitrogen blowing instrument XD-DCY-12S product features:
1, the gas distribution chamber needle channel can be used alone or in combination, each gas needle can be separately switch. A highly visible room needs adjustment.
2, each gas flow can be regulated separately, to meet the different needs of users. At the same time, overcome the weakness of the adjustable nitrogen blowing instrument of the gas gas flow, the size of the road.
3, Water nitrogen blowing instrument With self balancing suspension lifting system, unique design, make the distribution chamber height adjustment is more flexible and realize single hand operation.
4, water nitrogen blowing instrument is used in digital temperature control, digital display, regulating the use of PID technology and can realize the over temperature alarm.
5, may the solvent and the contact parts are made of 316 stainless steel materials, aluminum alloy and plastic sprayed surface, long service life and easy to clean.
6, the machine can be put into use in the hood.
7, you can choose each type of gas flowmeter.
The heating block size 8 general standard for the diameter of phi 15mm, special specification can be scheduled in advance of its special pore size and form.

12 square water nitrogen blowing instrument XD-DCY-12S The correct operation and matters needing attention
Operation of the use of water bath nitrogen blowing instrument before, should be familiar with the engineering process and steps. Rapid enrichment requires knowledge of the quantity of the sample, nitrogen flow rate, water bath temperature and the balance between the needle position. Improper use will be less effective, or even cause loss of sample or sample pollution. At the same time, pay attention to the environmental conditions of the air ventilation hood is polluted, the purity of nitrogen, sample transportation process.
Water bath operation
1 open water bath power switch.
2 set temperature. According to the temperature setting on the display panel on the left side of the first button on the display "SP", then click "V" or "V", is displayed as required under the set temperature value, but the first key left back again. Usually the water bath temperature should be less than the boiling point of the solvent temperature of 2-3 DEG C.
Nitrogen blowing instrument operation.
1 the nitrogen blowing instrument to ascend to the highest position, and the locking.
2 of the sample tube is placed into the sample positioning frame, sample positioning frame fixed spring tube, the bottom of the tube in a supporting tray, record the sample placement. If the support tray is too low, then loosen the two screws and the tray support center ring. Increased support tray, until the bottom of the tube in the tray, from the positioning frame is not less than 15mm. Adjust the support tray, the slit tube alignment. Re tighten screws, fixed support tray.
3 installation of stainless steel needle, can be directly set.
4 open the nitrogen cylinder, adjusting the flowmeter as nitrogen blowing instrument air. Nitrogen only need to open a little, otherwise too much pressure to open the pipeline. Adjust to the required pressure meter.
5 reduce the needle, the needle distance until the surface of the 6mm solution. Adjustment: lock nut unscrew the gas distribution plate, needle tube can slide up and down, adjust the height, tighten the lock nut.
6 open the valve like grade. Open the valve, the counterclockwise rotation of 1/8 to the 1/6 ring can not rotate too dramatically, to prevent the valve nut off, when installed, should rotate clockwise.
7 concentrated sample, recommended nitrogen air blowing 5-10min, to prevent the impurity gas residual nitrogen blowing instrument in the gas path.
8 meter blowing instrument to adjust the flow rate of nitrogen. Nitrogen blowing, with flow valve needle above the velocity tuning. And the monitoring of gas pressure, shall not exceed 200Kpa. Adjust the flow valve, the airflow ripples on the surface of the sample, but should prevent splash.
9 until the completion of continuous vaporization. According to the non drying boundary point requirements, the need to monitor the vaporization, arrive at the desired boundary after removal of the sample.
10 vaporization is completed, use clean Straw, rinse the stainless steel needle with one or two drops of solvent.
11 to slide on the needle tube, remove the sample from the sample positioning frame tube.
12 after the completion of the closure of gas vaporization.
13 turn off the flow meter and flow valve.
14 turn off the water supply.
15 remove the stainless steel needle.
12 square water nitrogen blowing instrument XD-DCY-12S Matters needing attention
(1) the nitrogen blowing instrument for ignition temperature below 100 DEG C material.
(2) the use of nitrogen blowing instrument, should protect hands and eyes.
(3) nitrogen blowing instrument should be used in the hood, to ensure good ventilation.
(4) heating without moving the nitrogen blowing instrument, to prevent burns.
(5) three line grounding power.
(6) not charged open water bath shell, to prevent electric shock.
(7) maintenance nitrogen blowing instrument shall be conducted by professional personnel, may be caused by improper components to replace nitrogen blowing instrument damage or security risks.
(8) like petroleum ether and other high flammable substances do not use nitrogen blowing instrument.
(9) do not use acidic or alkaline substances, otherwise it will damage the nitrogen blowing instrument.
