詳細介紹
東莞市源豐實驗科技有限公司專業(yè)代理美國Nist標準物質(zhì)
美國國家標準與技術(shù)研究院（National Institute of Standards and Technology，NIST）直屬美國商務(wù)部，從事物理、生物和工程方面的基礎(chǔ)和應(yīng)用研究，以及測量技術(shù)和測試方法方面的研究，提供標準、標準參考數(shù)據(jù)及有關(guān)服務(wù)。
美國NIST通過認證和提供1300多種具有良好特征的成分或性能的標準參考材料，或兩者兼?zhèn)?，從而支持準確和兼容的測量。這些材料作為整體質(zhì)量保證計劃的一部分，用于在單元中進行儀器校準，以驗證特定測量的準確性，并支持開發(fā)新的測量方法。
