Civil construction: The ground of the liquid chromatography room is generally the terrazzo floor and floor. The chromatographic table is 0.75 meters high and 0.80 meters wide. The table is 0.5 meters away from the wall. The terrazzo board is covered with rubber plates. It is not easy to place liquid chromatography and gas chromatography in one room. The liquid chromatography room should be equipped with a sample processing room, and the sample processing room should be equipped with a fume hood, water supply, and medicine cabinet.
Circuit: single-phase three-wire (fire, zero, ground), three-phase five-wire chromatographic chamber with many instruments.
Ventilation: There is organic gas in the liquid chromatography room, so there must be good ventilation. Install an exhaust hood above the instrument (as shown in the figure) and use a roof fan. Generally, the room is 400 mm high from the ground 200 mm below the corridor side wall × 400mm louver vents.
Room temperature: The temperature of the liquid chromatography room is generally required to be 22-27 degrees. The large laboratories use integrated air conditioning, and the air outlet of the air conditioning should be located in the upper part of the room.
