In April 2020, Aowei Instruments Green Laboratory Solution Products (solvent safety bottle caps, intubation type waste collection, funnel type waste collection) contributed to the green environmental protection of major laboratories in China. Not long ago, a laboratory in Southwest China found us to solve the problem of liquid chromatograph waste.
There is a liquid chromatograph in this teacher’s laboratory, and everyone knows that liquid chromatography is a type of separation and analysis technology. Its characteristic is that liquid is used as the mobile phase. The stationary phase can take many forms, such as paper, sheet and packed bed. The working principle is that the mobile phase flows through the injection valve through the infusion pump, is mixed with the sample solution, flows through the chromatographic column, is adsorbed and separated in the chromatographic column, and finally each component is converted into an electrical signal through a detector. The corresponding sample peak appears on the chromatographic workstation.
Because the teacher’s liquid chromatography processes a lot of mobile phases, like water phase: formic acid, acetic acid, perchloric acid, etc., organic phase: methanol, acetonitrile, dichloromethane, etc., and the main waste liquid collection of liquid chromatograph is mobile The waste liquid generated after the phase and liquid samples are adsorbed and separated in the chromatographic column is usually collected by ordinary solvent bottles. The odor generated after the waste liquid volatilizes is very serious. The entire laboratory environment is very bad and I have been trying to solve it. For this issue of liquid chromatography waste collection, the teacher immediately contacted us after seeing our product on the Internet.
The teacher chose our intubation waste collection product, because this product has very rich interfaces, Φ4-8 inner diameter hose, Φ1.6-3.2 outer diameter hard tube can be connected, and the bottle cap is optional Equipped with a variety of waste liquid filters can efficiently adsorb exhaust gas, the timing button can record the use time to remind replacement, the float level switch made of PVDF material can also accurately detect the liquid level to prevent the waste liquid from overflowing.
