Overview

Thermal analysis tube standard preparation instrument 1. Currently, methanol is mainly used as a solvent for liquid standard preparation, which requires manual dilution and preparation. Human factors have a significant impact, and different people have different results. 2. The methanol solvent in the liquid standard sample has a significant impact, and the separation of benzene is not good. 3. Manual dilution operation makes it easy for the human body to inhale harmful substances, posing a health hazard to the operators. 4. The liquid standard can only be used once after opening, wasting the standard. 5. According to the method requirements, liquid standard samples need to be purged with 50-100ml/min nitrogen gas at 50 degrees for 3-5 minutes, but currently the laboratory does not have this condition.

Product Details

Thermal Analysis Tube Standard Sample Preparation InstrumentPain points of standard curve preparation:

1. At present, the preparation of standard samples mainly uses liquid standard samples with methanol as the solvent, which requires manual dilution and preparation. Human factors have a significant impact, and the results may vary among different people.

2. The methanol solvent in the liquid standard sample has a significant impact, and the separation of benzene is not good.

3. Manual dilution operation makes it easy for the human body to inhale harmful substances, posing a health hazard to the operators.

4. The liquid standard can only be used once after opening, wasting the standard.

5. According to the method requirements, liquid standard samples need to be purged with 50-100ml/min nitrogen gas at 50 degrees for 3-5 minutes, but currently the laboratory does not have this condition.

Thermal Analysis Tube Standard Sample Preparation Instrument‍Advantage:

1. Automatic preparation of standard sample tubes using standard gas

2. No solvent interference, benzene derivatives respond more sensitively, with sharper resolution and peak shape

3. Save standard samples, one bottle of standard gas can be used for more than one year

4. No need for manual dilution and calibration, no organic solvent evaporation, protecting the health of operators

5. Quality flowmeter ****** controls the flow rate and volume of the standard sample, ****** linear******
