Planning requirements for special laboratories
(1) Processing with the sample: There is a sink, bench, fume hood, etc.
(2) Instrument room (spectrum room): room temperature (20±5) ℃, humidity (65±5)%.
(3) Ventilation: There is a local exhaust hood on the upper part of the instrument.
(1) Processing with the sample: There is a sink, bench, fume hood, etc.
(2)Instrument room: room temperature (20±5) ℃, humidity 60%~65%.
(3) Ventilation: The mercury vapor of the mass spectrometer escapes and is used for indoor local ventilation. The instrument must be higher than the local exhaust hood device.
(4) Water supply: The water pressure requirement is not less than 2kg/cm2.
Power supply: one-phase three-wire 110VAC, 220VAC and three-phase five-wire 380VAC.
(1) Processing with the sample: There is a sink, bench, fume hood, etc.
(2) Instrument room: room temperature (20±5) ℃, humidity (65±5)%; there must be a sufficient thickness of protective material, the protective door must have a signal processing device that opens by itself, and there must be a good ventilation Requires the supply of vacuum, compression and air and cooling water.
(1) Equipped with gas cylinder storage room.
(2) Instrument: room temperature (20±5) ℃, humidity (65±5)%; the chromatographic instrument has a solid station, and the device should be 600 mm from the wall station. In order to access the device, the partial row of the device The top of the air cap device.
(1) Processing with the sample: There is a sink, bench, medicine cabinet and other fume hoods.
(2) It should not be placed in the same room with liquid chromatography, gas chromatography and other instruments.
(3) Room temperature 22℃~27℃, humidity (65±5)%; the chromatographic instrument has a solid station, and the equipment should be 600mm from the wall station to facilitate the maintenance of the instrument.
(4) Gas path: Generally, companies have the following three types of gas paths (nitrous oxide, acetylene gas, compressed and air). The gas path enters the Chinese room through the cylinder storage room. The indoor main pipeline can be divided to each One chromatograph, add a needle valve before connecting each chromatograph. The gas company can use ambient air to compress the pump.
(5) Ventilation: The combustible gas of atomic absorption emits a large amount of carbon dioxide due to combustion. It should be well ventilated indoors, and a local exhaust hood should be installed above the instrument.
(6) Power supply: single-phase three-wire 110VAC, 220VAC and 380VAC power three-phase five-wire are required.
(1) Processing with the sample: There is a sink, bench, medicine cabinet and other fume hoods.
(2) Do not place it in the same room with instruments such as atomic absorption spectrometry and gas chromatography.
(3) Room temperature 22℃~27℃, humidity (65±5)%; the chromatographic instrument has a solid station, and the equipment should be 600mm from the wall station to facilitate the maintenance of the instrument.
(4) Ventilation: The liquid chromatograph has organically bound gases, and the interior design must have a good ventilation. We must have a local exhaust hood device above the instrument.
Power supply: one-phase three-wire 110VAC, 220VAC and three-phase five-wire 380VAC.
(1) Processing with the sample: There is a sink, bench, medicine cabinet and other fume hoods.
(2) It should not be placed in the same room with liquid chromatography, gas chromatography and other instruments.
(3) Room temperature 22℃~27℃, humidity (65±5)%; the chromatographic instrument has a solid station, and the equipment should be 600mm from the wall station to facilitate the maintenance of the instrument.
(4) Gas passage: 4 kinds of ships equipped with gas pipelines (nitrogen, hydrogen, helium, compressed air), the air route between the storage tank and the inside, the gas route adds a filter through the pipeline and enters the chamber for adjustment The valve totals each chromatograph, connected to each chromatograph of the front and needle valve. Available air compressors pump oxidant gas, and hydrogen can be used in hydrogen generators.
(5) The exhaust problem of the TCD detector needs to be connected to an outdoor with various pipelines.
(6) Ventilation: The chromatographic room has hydrogen and carbon dioxide released by combustion, and the room should be well ventilated.
(7) Power supply: single-phase three-wire 110VAC, 220VAC and 380VAC power three-phase five-wire are required.
The balance is a common method instrument necessary for chemical analysis laboratory.
High-precision balances have certain requirements for the environment: anti-vibration, dust-proof, direct sunlight, anti-corrosion gas erosion and constant temperature. Therefore, a special balance room is set up to meet the above requirements.
The balance room should be northward, and it should be far away from the source of vibration, and it should not be adjacent to the high-temperature greenhouse and the room with strong electromagnetic interference. The high-precision micro-analysis balance should be located at the bottom of society. The balance room should adopt this double-layer window, which is beneficial to improve the heat insulation and dustproof. The balance room should preferably be provided with a transition room to avoid the influence of airflow. It has air conditioning and the wind speed should be low. The interior design of the balance should not have a water basin or any other type of pipeline passing through the interior at the same time, so as to avoid leakage and condensation of the pipeline or affect the use and maintenance of the electronic balance when the pipeline equipment is overhauled. Try not to place unnecessary furniture to reduce the accumulation of dust.
