Reference Standard Sample Certificate

This series of high-purity metal standard samples is suitable for product quality inspection of pure metals and other materials, calibration of measuring instruments, evaluation of measurement methods, and unified testing values. It can also be used for impurity analysis, purity determination, and preparation of standard raw materials for such products.
1、 Sample preparation:
This series of standard substances is selected from high-purity copper, high-purity lead, pure zinc, pure tin, pure bismuth, pure antimony, pure cadmium, pure nickel, pure cobalt, pure aluminum, pure magnesium, pure silicon, pure titanium, pure manganese, pure gallium, pure selenium, pure pounds and other raw materials. After purification, the purity and impurity content are determined by classical methods such as inductively coupled plasma emission spectroscopy or inductively coupled plasma mass spectrometry. The preparation process is as follows: raw material selection → purification → processing into chips or blocks → mechanical mixing → initial uniformity inspection → packaging → uniformity retesting → mathematical statistics → constant value.
2、 Uniformity and inspection:

Randomly select 20 bottles from the packaged samples and use the variance F-test method. The results show that the sample uniformity is good. Testing method: Inductively Coupled Plasma Atomic Emission Spectroscopy. Zui small sample size: 0.5 grams. After investigation, this standard sample has good stability and a validity period of ten years.
3、 Packaging. Usage and storage:
1. Bottled. Plastic seal, tighten the bottle cap after use, store in a dry place, and store in a dryer
2. Pure copper and pure manganese are prone to oxidation. Before use, wash the surface oxide layer with 5% dilute nitric acid, wash it with distilled water in a timely manner, and then clean it with anhydrous ethanol. Use qualitative filter paper to absorb surface water, and use a hair dryer to heat and dry it slightly before use.
3. If the surface of pure titanium changes color due to oxidation, wash the surface oxide layer with 5% phosphoric acid before use, wash it with distilled water in a timely manner, and then clean it with anhydrous ethanol. Use qualitative filter paper to absorb the surface water, and dry it with a hair dryer at a slight temperature before use.
