Impact of Environmental Conditions on Reagent Shelf Life
1. Effect of Air: Oxygen in the air can easily oxidize and degrade reducing reagents. Strong alkaline reagents tend to absorb carbon dioxide and convert into carbonates; moisture can cause certain reagents to deliquesce or form clumps; fibers and dust can reduce or discolor certain reagents.
2. Effect of Temperature: The rate of reagent deterioration is related to temperature. High summer temperatures accelerate the decomposition of unstable reagents; severe winter cold promotes the polymerization of formaldehyde, leading to precipitation and deterioration.
3. Effect of Light: Ultraviolet rays in sunlight can speed up chemical reactions in certain reagents, causing deterioration (e.g., silver salts, mercury salts, bromine and iodine salts of potassium, sodium, ammonium, and certain phenolic reagents).
4. Effect of Impurities: The purity of unstable reagents significantly impacts their deterioration. For example, pure mercury bromide is practically unaffected by light, whereas mercury bromide containing trace amounts of mercurous bromide or organic impurities tends to turn black when exposed to light.
5. Effect of Storage Period: Unstable reagents may undergo disproportionation, polymerization, decomposition, or precipitation after long-term storage. During the storage period and within the validity period, if liquids exhibit abnormalities such as layering, turbidity, discoloration, or mold growth, or if the retention time or relative retention time of samples changes significantly when the mobile phase is used for sample testing, or if solids show abnormalities like moisture absorption or discoloration, they should be discontinued.
