Due to the fact that most ferroalloys can form cosolubles with platinum at high temperatures, which seriously corrode platinum crucibles, sufficient preoxidation is required And recently a large stainless steel production enterprise, due to the raw material powder sheet often drop powder, pollution analysis equipment, Change to molten sample preparation, and provide samples to request our help in developing the molten sample method View more >>

X-ray fluorescence spectrometry (XRF) has been widely applied in geology, metallurgy, environment, building materials and other fields because of its simple preparation, high precision and multi-element simultaneous determination The powder pressing method is to put into special molds the powder sample which has been dried or roasted, ground an View more >>

The water chiller, also called chiller, is a kind of water cooling equipment that can provide constant temperature, constant current and constant pressure At present, there are many kinds of water chillers in the market, but the quality is uneven, and the price is even different Then how to purchase a suitable water chiller for the lab View more >>

XRF analysis is actually a surface analysis method Excitation occurs only on the shallow surface of the sample, so it must be noted whether the analysis surface is representative of the entire sample The average granularity and granularity distribution of the sample are of great impor......View more >>

Powder pressing method is simple, fast, and low-cost It is suitable for trace analysis of medium and heavy elements as well as the determination of main, secondary, and trace elements in the relatively consistent category with no high accuracy requirements As one of the commonly used sample preparation methods for XRF analysis, View more >>
