Overview
SRM 640g Silicon Powder Standard (SRM 640f new batch) Line Position and Line Shape Standard for Powder Diffraction Specification: 7.5 g is used to calibrate the line position and contour width of powder diffraction equipment as a function of 2 θ angle.
Product Details
SRM 640g Silicon Powder Standard (SRM 640f New Batch) Introduction:
SRM Number: SRM 640g(SRM 640f 新批次）
Description:Line Position and Line Shape Standard for Powder Diffraction (Silicon Powder)
Chinese description: Silicon powder standard (silicon powder diffraction standard)
Unit of Issue（规格）：7.5 g
The certification values provided by this standard reference material (SRM) are used to calibrate the line position and contour width of powder diffraction equipment as a function of the 2 θ angle.
One unit of SRM 640g is composed of approximately 7.5g of silicon powder and bottled under argon gas.
Validity period: The certification value provided by SRM 640g is valid indefinitely within the specified measurement uncertainty range. If the material is stored or used improperly, damaged, contaminated, or otherwise modified, the certification value will become invalid. There is no need to periodically re certify this SRM.

storage
SRM 640g is bottled under argon gas to prevent moisture. When not in use, tightly seal the unused portion of this powder in the original bottle or store it in a similar or more moisture-proof manner.
Usage:
The sample loading of the Prague Brentano diffractometer should achieve a powder bed with high packing density and flat surface.
