Why peristaltic pumps are required for atomic spectroscopy?

There are three main reasons:

  1. Using Lead Fluid peristaltic pumps can effectively prevent measurement errors caused by cross-infection of samples. When the Lead Fluid peristaltic pump transfers fluid, the fluid only flows in the hose, and there is no need for valves and seals in the fluid path to avoid dead ends in the fluid path, so the fluid path is easy to clean and there is no sample residue.
  2. Using Lead Fluid peristaltic pump can realize continuous and stable transmission, and the transmission accuracy is high.
  3. The use of Lead Fluid peristaltic pump can effectively control the cost. Realize the ratio of multiple reagents at a lower cost.

Atomic Spectroscopy pump head

A atomic spectrometer is a scientific instrument that decomposes light with complex components into spectral lines, and through the capture and analysis of light information, it can detect which elements are contained in the article.

For example, the seven-color light in sunlight is the part that can be seen by the naked eye (visible light), but if the sunlight is decomposed by a spectrometer and arranged by wavelength, the visible light only occupies a small range in the spectrum, and the rest are the spectrum that the naked eye cannot distinguish. . Such as infrared, microwave, ultraviolet, X-ray and so on.

There are many types of spectrometers. Common spectrometers include: atomic emission spectrometer, atomic absorption spectrometer, molecular absorption spectrometer, atomic fluorescence spectrometer, infrared spectrometer, Raman spectrometer, etc.

Spectrometers are widely used in the detection of air pollution, Waste water, food hygiene, metal industry, etc.

Why do we use peristaltic pumps for atomic spectrometer?

The spectrometer needs to use the fluid delivery function of the peristaltic pump to push the sample reagent into the instrument to react.

There are many methods for reagent injection, here are two more commonly used injection methods.

  1. Continuous flow method:

Using the sample-sample-sample injection method, different samples are continuously and uninterruptedly transported to the reaction module through a peristaltic pump, so that the samples continue to react.

  1. Intermittent flow method:

The computer is used to control the speed and time of the peristaltic pump, and samples and blanks are alternately input into the instrument. It has the characteristics of good stability, high precision, small sampling volume, and easy operation. After being equipped with an autosampler, the operation can be automated, and it is widely used by domestic instrument manufacturers.
