Application
It is used for quality assurance and quality control in environmental monitoring and analytical testing, and can also be used for instrument calibration, method verification and technical arbitration.
Sample Preparation
This standard substance uses dichloroacetic acid whose purity has been accurately determined as the solute and methanol as the solvent. It is prepared by the weight-volume method in a clean laboratory at room temperature of 20±3°C.
Traceability and valuation method
The concentration standard value of this standard substance adopts the prepared value, and the value is checked by gas chromatography. Through the use of preparation, measurement methods and measuring instruments that meet the requirements of metrology characteristics, the traceability of the quality value of the standard material is guaranteed.
Characteristic value and expanded uncertainty
|
The expanded uncertainty of the standard value is mainly synthesized by the uncertainty of raw material purity, weighing, constant volume, uniformity, and long-term stability.
Packaging, storage and use
Packaging: This standard substance is packaged, and the specification 1.2ml should be protected against chipping when carried or transported. Storage and use: Keep refrigerated and protected from light. Before use, it should be balanced at room temperature (20±3℃) and shaken sufficiently to ensure uniformity. Once the ampoule is opened, it should be used immediately. It cannot be used as a standard substance after being re-sealed. Strictly prevent contamination during use.
