The results obtained in the study of the precision of the determination of calibration factors in carbon, hydrogen, and nitrogen microanalysis by combustion-gas chromatography and in oxygen microanalysis by pyrolysis-gas chromatography are reported. The variation of the parameter counts (-blank)/gmg ...
In this paper, a new calibration apparatus has been developed for gas micro-flow calibration. The apparatus employs both the constant volume method and the constant conductance method. The calibration range from 10(-1) to 10(-13) Pa.m(3)/s, and the combined standard uncertainty is 1.2%...
For the calibration of comet mass spectrometers a novel calibration system was designed to simulate the neutral gaseous atmosphere of comets. The facility consists of a fully automated three-chamber ultra-high vacuum system with a separate gas mixing unit. The molecular beam technique is used for ...

Then, once the two components are brought together in the final device, the calibration of the whole device is required as well. It may be necessary to also perform a calibration of the software, perhaps performed at preset intervals, even just once to ensure that the sensor is mounted in ...
For calibration data, the grain yield and RIHarvest were more variable across fields (CV = 36–37%) than the relative plant height and RI based on plant height (RIHeight) (CV = 14–17%). The black soil field had similar variation (CV = 30–36%) as the aeolian sandy soil field (...
