(The customer's information and samples need to be kept confidential, this case only reflects part of the information)
For the analysis of the composition of unknown samples, multiple instruments and multiple spectrums need to be mutually verified to ensure the accuracy of the report.
Background of the project:
Drilling fluid fluid loss agent, also known as fluid loss agent, is an additive used to reduce the fluid loss of drilling fluid or the loss of liquid phase leakage into the formation. A customer provides fluid loss additives specifically for the drilling industry. When blending such fluid loss additives, a certain important raw material, polymer powder, is added. This polymer powder is white, in line with national environmental protection standards. This company entrusts us to do the component analysis of the polymer powder to see which substances are mixed and what the specific ratio is.

Rectifier Diode(Standard Diode)
Rectifier Diode(Standard Diode) utilizes the unidirectional conductivity of the diode, which can convert the alternating current of alternating direction to a pulsating direct current of a single direction. Rectifier diode – diode designed for rectifying alternating current (mostly with low power frequency – 50 Hz at high power emitted during load). The main task of the rectifier diode is to convert AC voltage into DC voltage through application in rectifier bridges. The variant of rectifier diodewith the Schottky barrier is particularly valued in digital electronics.
