一般說明

方法:光度法,0.002 - 1.00 mg/l NO₂-N 0.007 - 3.28 mg/l NO₂⁻ Spectroquant®
该方法类似于EPA 354.1、APHA 4500-NO2- B和DIN EN 26 77。
该Spectroquant®硝酸盐比色池测试可以准确定量水样中的硝酸盐。硝酸盐是动植物生长所需的必需营养素。但是,硝酸盐水平升高可能会危害健康,特别是对怀孕妇女和婴儿而言。因此,许多国家都对水源中的硝酸盐水平进行了监管。
方法原理:在酸性溶液中,硝酸盐离子与磺胺酸反应形成重氮盐,它与N-(1-萘基)-乙二胺二盐酸盐反应形成可用光度法测定的紫红色偶氮染料。
该Spectroquant®试剂测试盒包含高度稳定的即用型试剂混合物,用于根据随附说明书所述流程进行分析。
我们所有的比色池和试剂测试盒都配备了独特的实时ID(2维码),可实现无缝方法识别,并包含相关必要信息,例如批号、有效期和自动校准更新。

應用


  • Clinical and laboratory features of urinary tract infections in young infants: Discusses diagnostic challenges and characteristics of urinary tract infections in infants, stressing the importance of accurate detection to guide treatment (Lo et al., 2018).

  • Differentiating Kawasaki disease from urinary tract infection in febrile children with pyuria and C-reactive protein elevation: Focuses on differential diagnosis in pediatric care, which can influence the choice of nitrite tests for accurate and timely diagnosis (Han and Lee, 2018).

  • Early features of Kawasaki disease with pyuria in febrile infants younger than 6 months: Addresses the overlap of urinary symptoms in Kawasaki disease, underscoring the utility of nitrite tests in complex cases (Yoon et al., 2018).

  • Current practice on the management of pre-operative urine dipstick results in women undergoing gynaecological surgery in Wales: Reviews procedures related to pre-surgical care in gynaecology, indicating broader applications of nitrite testing in hospital protocols (Walker et al., 2019).
