我们维克奇专门做标准品/对照品的,产品纯度要大于等于百分之九十八,可以看看我们的网站信息
试验中的“空白试验”,是指在不加供试品或以等量溶剂替代供试液的情况下,按同法操作所得的结果。其作用是排除实验的环境(空气、湿度...)、实验所用的药品(指示剂等等)实验操作(误差、滴定终点判断之类的)对实验结果的影响。
试验中的“空白试验”,系指在不加供试品或以等量溶剂替代供试液的情况下,按同法操作所得的结果;含量测定中的“并将滴定的结果用空白试验校正”,系指按供试品所耗滴定液的量(ml)与空白试验中所耗滴定液量(ml)之差进行计算。
标准品,即标准物品,是中药标准对照品研究中心代理的作为一种衡量标准;用做药物方面,则为含量测定中的标准含量。标准品包括化学计量标准品、冶金标准品和药检标准品。
Reference material, accompanied by a certificate, one or more of whose property values are certified by a procedure, which established its traceability to an accurate realization of the unit in which the property values are expressed, and for which each certified value is accompanied by an uncertainty at a stated level of confidence. (Brammer StandardBASARMIetc). (ISO Guide 30-1992)
标准品CRM:标准物质/标准品附带析证书属性值某项或若干项都按照某程序进行验证验证程序建立些属性值所表述体系精确体现追溯性每经验证数值都伴随着某特定置信水平确定度(BS,NISTBASARMI等)(ISO Guide 30-1992)
Reference Materials(RM)
Materials or substance one or more of whose property values are sufficiently homogeneous and well established to be used for the calibration of an apparatus, the assessment of a measurement method, or for assigning values to materials. (ISO Guide 30-1992)
照品RM:种原料或物质其某种或几种属性值表现充均性并且用于设备校准析评估或者物质定植(ISO Guide 30-1992)
