松果菊苷,化學(xué)對(duì)照品(20mg)做好經(jīng)常性保養(yǎng)工作：
1、在正常儲(chǔ)存條件下，一般化學(xué)試劑貯有不宜超過(guò)2年，基準(zhǔn)試劑不超1年。
2、經(jīng)常檢查儲(chǔ)存中的化學(xué)試劑的存放狀況發(fā)現(xiàn)實(shí)際起過(guò)的儲(chǔ)存期或變質(zhì)應(yīng)及時(shí)報(bào)告，并按規(guī)定妥善處理和銷(xiāo)帳。
3、化學(xué)試劑的變質(zhì)，大多數(shù)情況是因?yàn)槭芡饨鐥l件的影響，如空氣中的氧氣、二氧化碳、水蒸氣、空氣中的酸堿性物質(zhì)以及環(huán)境 溫度、光照等都可使化學(xué)試劑發(fā)生氧化、還原、潮解、風(fēng)化、析晶、稀釋、銹蝕、分解、揮發(fā)、升華、聚合、發(fā)霉、變色以及燃爆等變化。
