The best test condition of combustion-infrared absorption spectrometry was determined thus: optimal sample weight of 0.0500g, combustion time of 25s, analysis time of 40s and oxygen analysis flow rate of 4.0L/min. The detection limit of combustion-infrared absorption spectrometry was 10×10-6 and...
combustionThis paper researched heat release rate testing technology based on TDLAS oxygen analyzer and paramagnetic oxygen analyzer, and researched the test data of the two systems when testing the oxygen concentration of air and the combustion exhaust gas. Experiments showed that, the TDLAS testing ...
Connector types such as board-to-board, wire-to-board, and wire-to-wire are widely used inside medical devices, and ruggedized versions of common USB, HDMI, and D-sub connectors add user-friendliness to these technologies. High quality versions of common connectors can also meet medical industr...
In order to ensure the accurate separation of particle sizes, the size partitioning of soil particles was verified immediately after the separation by a laser particle size analyzer (Mastersizer2000, Malvern, UK). The soil with different particle sizes was dried at 50℃, and then it passed ...

The identity of which driver substitutions will appear within a given tumor is determined by both somatic muta- tion patterns and by natural selection1–5. Different tumors may substantially vary in the biases of their mutational process, as a function of their type (e.g. lung vs colon) as...
An RGA (Residual Gas Analyzer) analyzes the chemical composition of gases in a vacuum by ionizing the gases to generate ions. It then measures the mass-to-charge ratio of these ions to identify the gases present. Spot Leak Detectors
It is suitable to make the main hydrocarbon of liquid petroleum products shown on the silica gel adsorption column with fluorescent indicator. Then calculate it's volume percentage. This will be regarded as the quality measurement index of engine fuel...
