[Multiple Choices) The following method is the most effective one to mitigate peak broadening in the Gas Chromatography technique: increasing injection volume. O increasing oven temperature. decreasing injection volume. O increasing injector temperature. [Multiple Choices) The ratio between eluent trajectory length and sample trajectory length is the definition of O retention factor. O signal to noise ratio. O retention time. O limit of detection. [Multiple Choices) Mobile phase polarity can affect O response factor. separation quality. O peak height. peak area. [Multiple Choices) Certain phenomenon that occurs inside gas chromatography detector is sample evaporation. O pressure increase of sample. Osample adsorption into detector. sample combustion. [Multiple Choices] The most appropriate criterion of the calibration curve is o having straight line shape. O having correlation coefficient (R2)= 1 O starting from (0,0) point crossing all calibration points
