LC-2900 liquid chromatography instrumentIt refers to an instrument that uses the difference in the distribution ratio of a mixture between liquid-solid or immiscible two liquids to separate the mixture first, and then analyze and identify it. According to whether the stationary phase is liquid or solid, it can be divided into liquid-liquid chromatography (LLC) and liquid-solid chromatography (LSC). The modern LC-2900 liquid chromatograph consists of a high-pressure infusion pump, an injection system, a temperature control system, a chromatographic column, a detector, a signal recording system, and other components. Compared with classical liquid column chromatography devices, it has the characteristics of being fast, sensitive, etc.

The environment is one of the main factors affecting the stability of LC-2900 liquid chromatography. Therefore, users must pay attention to the environmental conditions when using the LC-2900 liquid chromatograph.

1. Be careful to prevent interference.

Be careful to prevent interference from electricity and magnetic fields. The interference of electric and magnetic fields has an impactLC-2900 liquid chromatography instrumentAn important factor in stability. Generally speaking, the room of the security LC-2900 liquid chromatograph should be kept away from electric and magnetic field interference.

2. Pay attention to moisture prevention and moisture proofing

The LC-2900 liquid chromatograph is a high-tech product that integrates optics, mechanics, electronics, and computer technology, and every part of it is not allowed to be affected by moisture. Otherwise, it will damage or deteriorate the performance of the relevant components, affecting the stability of the instrument.

3. Pay attention to preventing dust from contaminating optical components

Many detectors of LC-2900 liquid chromatography are optical analytical instruments, and these optical components are easily contaminated by dust. Once the optical components are contaminated, it can cause a lot of trouble. Similar to the effect of moisture on optical components, it mainly reduces the reflectivity of optical components, thereby affecting the sensitivity of LC-2900 liquid chromatography instrument. In addition, it will also increase stray light, noise, reduce the sensitivity of the detector, and increase the error of analysis and testing. Therefore, the room where the LC-2900 liquid chromatograph is placed should be clean, ventilated, dust-proof, and also pay attention to preventing vibration.

The liquid chromatography system consists of many key technical indicators, such as noise, detection limit, stability, and repeatability. Users should regularly check these technical indicators, once every quarter or even once a year. If there is a problem with that technical indicator, users should not act rashly and should immediately request assistanceLC-2900 liquid chromatography instrumentThe manufacturer's maintenance engineer comes to repair the instrument, ensuring that it always works in the * state and analyzing the reliability of the test results.

Some users have noticed a problem together, but still insist on making it work. By doing so, on the one hand, the data analyzed and tested by the instrument is unreliable, and on the other hand, it is also easy to further damage the instrument.

In addition, the LC-2900 liquid chromatograph should be installed in a place where it cannot be directly exposed to sunlight to avoid strong room light, which may affect the effectiveness and service life of the instrument. Attention should also be paid to preventing rusting of mechanical components.

　　LC-2900 liquid chromatography instrumentThere are many rotating components, such as reciprocating pumps, grating scanning mechanisms for detectors, transmission mechanisms for slits, deuterium lamps for ultraviolet detectors, and light source conversion structures. Users should regularly add some clock oil to these moving parts to ensure their smooth operation. Some components are not easily accessible to users, and maintenance engineers or experienced technicians from the manufacturing plant can be sought to assist with maintenance.
