1. A method for identifying a sample comprising:
collecting a sample in a sample cylinder;
directing the sample from the sample cylinder to a tube, using a pressure control system disposed between the sample cylinder and the tube, such that a pressure in the tube is at a same level as a pressure in the sample cylinder;
identifying a phase of the sample and increasing the pressure in the tube to observe phase change of the sample;
identifying whether or not oily sludge or black particles exist in the sample through a transparent portion of the tube;
analyzing the sample using gas chromatography if neither oily sludge nor black particles are identified through the transparent portion of the tube, and
filtering the sample if oily sludge and/or black particles are identified through the transparent portion of the tube.
