pH buffer solution pH標準緩沖溶液

  l  緩沖溶液

  l  袋裝緩沖液

  l  濃縮緩沖液

標準物質是直接影響測定準確度的重要因素。此外,重復的測定成本昂貴并且浪費時間。這是新藍景為客戶提供認證緩沖物質和溶液的原因。

最高品質的二級標準緩沖液最大誤差是±0.003PH單位,非常精確并且適合用于儀器監控

即用型緩沖溶液和Titrisol縮液

即用型緩沖溶液的認證測量不確定值是0.015 pH單位,非常適合日常實驗室使用。同樣,Titrisol濃液的測量不確定值是0.02 pH單位.

即用型袋裝緩沖液

即用型袋裝緩沖液不僅可以確保結果精確,而且有不易污染和保持新鮮的優點。

新藍景擁有自己的PH測定校準實驗室

新藍景自己的pH測定校準實驗室已經經過校準協會(DKD) DKD-K-14301,方法認證,而且接受DKD或聯邦物理技術研究所(PTB]的嚴格審計。所有新藍景的緩沖物質和溶液都接受這個實驗室的質里檢側。

質量控制

新藍景二級標準物質經過雙鉑氫電極示差電勢測定法檢測。該方法測定pH的總體不確定值最大是±0.003 pH單位,因此緩沖液配制可以非常的精確。

為了確保即用型緩沖溶液.Tritisol 濃縮液或袋裝液的精確測量,新藍景采用了5點校準法(精度為≦±0.015個pH單位或者±0.02個pH單位);這種方法比簡單的2點法校準精度(≥0.05 pH單位)更高。

溯源性

我們的標準物質可以直接溯源到美國國家標準與技術研究所(NIST)和聯邦物理技術研究所(PTB]的一級標準物質,因此PeltoPUR標準緩沖物質和溶液具有雙重溯源性。

PeltoPUR二級標準緩沖溶液(25 `C) PeltoPUR Secondary standard buffer solution(25 `C)

該系列產品用于校準并監控PH測定儀。

最大誤差僅有0.003pH單位。每個PeltoPUR產品都在它的COA中提供有相關數據。

為您提供精確并節省時間和成本的產品。

新藍景公司提供給PT8分析用的緩沖物質,PT8在經過嚴格的測定后再將它們制成基準物質。這樣的基準

物質對于客戶來說過于昂貴,因而新藍景采用同樣的原材料制成二級標準物質提供給客互,并用基準物質

對其比較定值。

此外。PeltoPUR緩沖液/物質均通過NIST的一級標準物質比較定值。
