With the gradual decline of the epidemic situation, most enterprises have begun to return to work.
As a high-quality service provider, steadfast Deyan will certainly move forward with the enterprise, and Thermal analyzer Users provide better solutions.
Thank you for your attention Reliable manufacturers in Beijing The trust and support of Deyan Instrument Co., Ltd.
On August 1, the state will implement the new standard GB 50325-2020. In order to ensure the normal use of the instrument under the new standard GB 50325-2020, our company will provide the upgrading and maintenance service for the ex factory thermal analyzer in order to ensure the normal use of the instrument under the new standard GB 50325-2020.
Steadfast to the factory heat analysis The instrument meets the requirements of GB 50325-2010 code for indoor environmental pollution control of civil construction engineering, hj583-2010 solid adsorption / thermal desorption gas chromatography and hj644-2013 determination of volatile organic compounds in ambient air The standard application requirements include adsorption tube sampling thermal desorption gas chromatography-mass spectrometry, hj734-2014 determination of volatile organic compounds in waste gas from stationary pollution sources solid phase adsorption thermal desorption / gas chromatography-mass spectrometry.
According to the new edition of GB 50325-2020, the target substance of TVOC test is n-hexane ~ n-hexadecane, with a total of 16 substances.
The standard clearly requires quantitative detection of n-hexadecane, and the boiling point of this component is about 287 ℃, which is very easy to condense analysis There are higher requirements for sample pipeline and trap, otherwise it is difficult to be linear.
Heat analysis However, it may not be affected by the new standard of "325-50gb" for the fine particles in the standard of 325-50gb.
In order to meet the new detection standard, we suggest to replace the injection system, injection valve, trap, etc, Company software upgrades are free of charge.
Our company in order to ensure the interests of users, the hot purchase after 2019 analysis Free upgrade and maintenance of the instrument; hot purchase before 2019 analysis The instrument is charged with the cost of parts for upgrade maintenance (please contact us for details).
