1. Main uses of nitrogen blowing instrument:
It is used to remove a little volatile liquid, such as water and some organic solutions, which are often used in the laboratory. The typical use of nitrogen blowing instrument is in the detection of solid-phase extraction - Meteorological chromatograph. After the solid-phase extraction is taken out, the nitrogen blowing instrument can be used to scrape away most of the saturated solution in the flushing solution, that is, the whole process of concentration is completed, and then the gas phase inspection can be carried out on the machine.
2. What is the use of nitrogen source for nitrogen blowing instrument?
If the demand is large, it is recommended to buy a nitrogen generator;
Nitrogen blowing instrument is indispensable for testing some new items, and high-purity nitrogen can be used;
Generally, the nitrogen in the climate is more than 99.99%, and 2-3 nitrogen can be used.
3. In what tests will nitrogen blowers be used?
The nitrogen blowing instrument uses rare gas to purge the heated sample solution. The superimposed constant temperature oscillation incubator enables the untreated sample to be quickly concentrated. The manufacturer of the water separated constant temperature incubator achieves the practical effect of rapid separation and purification. This method is simple to use, especially when several samples can be solved at the same time, which greatly shortens the field sampling.
4. Four advantages of nitrogen blowing instrument
Nitrogen blowing instrument is also called full-automatic rapid concentration instrument, nitrogen drying instrument, etc. At this stage, the artificial climate chamber light incubator has already replaced the traditional rotary evaporators. Compared with the traditional rotary evaporator, the nitrogen blowing instrument has the following advantages:
The rotary vaporizer may cause damage to the sample when the organic solvent is boiled, while the nitrogen blower is accurate and smart during concentration to prevent damage to the sample.
The nitrogen blowing instrument can solve several samples at one time, and its advantages can be highlighted in the repeated experiments of multi-level and multi elements.
In the test, the operator does not need long-term maintenance, which can reduce human resources.
The experimental process is simple and convenient. The concentration process can be adjusted at any time.
