[Multiple Choices] Main function of the chromatography column is O detecting sample. changing sample phase. separating sample from eluent. O reducing sample pressure. [Multiple Choices] The following method is the most effective one to mitigate peak broadening in the Gas Chromatography technique: O increasing oven temperature. o increasing split ratio. increasing injection volume. o increasing injector temperature. [Multiple Choices] The driving force of substance separation in chromatography technique is substances molecular weight differences. O substance polarity differences. substance boiling point differences. O substance affinity differences towards selected column. [Multiple Choices] Following statement is correct for gas chromatography column: O columns is designed to utilize adsorption-desorption phenomenon of mobile phase towards it. O column is a place where evaporation occurs. column is a capillary pipe inside GC equipment. O column acts as a mobile phase. [Multiple Choices] The following statement is correctly defining the chromatography column: O chromatography column is a chamber to detect the sample. each analyzed sample that passes through must be in a gas phase.. O any leftover substance in it is tolerable. O any chemical reaction occured in it is tolerable
