Improve the accuracy of the protein analyzer from the beginning of the sample crushing
We know that in many industries, it is necessary to use a protein analyzer to determine the content of a sample protein, and the measured data result is of great significance for evaluating the quality of a sample. Therefore, how to ensure the measurement accuracy of a protein analyzer is an industry inspection personnel. Problems that must be considered. From the measurement process we can see that the determination of the protein analyzer is usually started from the crushing of the sample, so to improve the accuracy of the protein analyzer measurement, you can start from the crushing of the sample, the following will briefly introduce the sample crush There are four points that must be mastered.
The protein analyzer determines the protein content of the sample, which is strictly required for the sample. The measurement requires the sample to be crushed and all over a 40-mesh sieve. The purpose is to make it homogenous, easy to dissolve, and easier to digest. Therefore, in order to achieve this, we should pay attention to the following points in sample smashing:
1, due to smashing or sieving process, the sample is easy to produce automatic grading, such as corn, the hard part often gather in the above, soft parts gathered in the following. Therefore, after sifting and sifting, re-mix evenly so as to reduce measurement error;
2. The smashing process should be fast to avoid changes in the composition of the sample;
3. After crushing, there will always be a small part left in the crusher. This part cannot be discarded, otherwise it will affect the homogeneity of the sample;
4, for the full price of materials (even full-granular materials) and concentrates, no need to smash, of course, this is based on the good mixing uniformity of the mixer if you take to crush, will lose part of the powder material, and grading after grading Instead, the homogeneity of the sample is reduced.
With the development of modern science and technology, the degree of automation and measurement accuracy of protein analyzers are very high. However, if the test results are inaccurate due to sample non-compliance, which affects the correct quality judgment, then it is actually a little unprofitable, and therefore increasing protein levels. The accuracy of the analyzer measurement starts with the crushing of the sample, focusing on each operating detail.
Chlorinated polyethylene is a saturated polymer material with a white powder appearance. It is non-toxic and tasteless. It has excellent weather resistance, ozone resistance, chemical resistance and aging resistance. It has good oil resistance, flame retardancy and coloring properties. It is an excellent impact modifier for PVC plastics and a synthetic rubber with good comprehensive performance. It has a very wide range of applications and has been widely used in cables, wires, hoses, tapes, rubber and plastic products, sealing materials, flame retardant transport belt , Waterproof coiled material, film and various profiles and other products.
As a PVC impact modifier, CPE135A has many advantages such as low price, excellent performance, and excellent aging resistance, but it has certain disadvantages in the use of high impact and high hardness products and low temperature resistant products CPE135A. For example, in the formulation of rigid PVC, a large amount of CPE will reduce the hardness and rigidity, which reduces the physical properties of the product; in addition, when the low temperature resistance requirement of PVC products exceeds minus 30°C, CPE135A cannot meet the requirements. Under normal circumstances, modified CPE, such as ACM, RGC135A, etc., can be selected for rigidity and hardness improvement; for low-temperature resistance modification, impact-resistant ACR or other impact modifiers with lower glass transition temperature can be selected.
