• 介紹：

     本標(biāo)準(zhǔn)物質(zhì)主要用于測(cè)量?jī)x器校準(zhǔn),分析方法評(píng)價(jià)和質(zhì)量控制,以及藥品、食品等相關(guān)領(lǐng)域相應(yīng)成分含量測(cè)定。

   

  一、樣品制備

  本標(biāo)準(zhǔn)物質(zhì)候選物是通過(guò)定制相應(yīng)阿魏酸純品，采用重結(jié)晶、柱層析等方法進(jìn)一步純化后制得，經(jīng)化學(xué)結(jié)構(gòu)定性分析和初步理化分析滿足要求后，進(jìn)行干燥分裝。

  阿魏酸：CAS號(hào) 537-98-4

   

   

  二、溯源性及定值方法

  經(jīng)方法確認(rèn)研究，本標(biāo)準(zhǔn)物質(zhì)采用高效液相色譜法-二極管陣列檢測(cè)器(HPLC-DAD)和定量核磁兩種不同原理方法定值方式測(cè)定候選物質(zhì)純度。通過(guò)使用滿足計(jì)量學(xué)特性要求的制備方法,測(cè)量方法和計(jì)量器具,保證標(biāo)準(zhǔn)物質(zhì)的量值溯源性。

   

   

  三、特性量值及不確定度（不同批次略有差別，詳見證書）

  編號(hào)	名稱	標(biāo)準(zhǔn)值（%）	不確定度（%）(k=2)
  BW10001	阿魏酸	99.93	0.02

  標(biāo)準(zhǔn)值的不確定度綜合考慮了主體純度定值結(jié)果、均勻性、穩(wěn)定性等引入的不確定度分量。

   

   

  四、均勻性檢驗(yàn)及穩(wěn)定性考察

  參照國(guó)家標(biāo)準(zhǔn)JJG 1006-94《一級(jí)標(biāo)準(zhǔn)物質(zhì)技術(shù)規(guī)范》，隨機(jī)抽取分裝后的樣品，采用高效液相色譜法-二極陣列檢測(cè)器(HPLC-DAD)對(duì)候選物進(jìn)行均勻性檢驗(yàn)、穩(wěn)定性考察，檢驗(yàn)結(jié)果表明均勻性和穩(wěn)定性良好。

  本標(biāo)準(zhǔn)物質(zhì)最小取樣量為5mg。

  本標(biāo)準(zhǔn)物質(zhì)有效期2年，研制單位將繼續(xù)監(jiān)測(cè)該標(biāo)準(zhǔn)物質(zhì)的穩(wěn)定性，有效期內(nèi)如發(fā)現(xiàn)量值變化，將及時(shí)通知用戶。

   

   

  五、包裝、運(yùn)輸和貯存、使用及注意事項(xiàng)

  1.包裝: 本標(biāo)準(zhǔn)物質(zhì)采用硼硅酸鹽玻璃安瓿瓶包裝，每瓶不少于50mg。

  2.運(yùn)輸和貯存: 冰袋運(yùn)輸,運(yùn)輸時(shí)應(yīng)避免擠壓,碰撞；冷藏條件下貯存。

  3.使用: 標(biāo)準(zhǔn)物質(zhì)開封后，應(yīng)盡快使用；二次使用不能再做標(biāo)準(zhǔn)物質(zhì)使用。
