应用
Fluoride Standard Solution can be used to check the photometric measurement system (reagents, measurement device, handling) and the mode of working.
特点和优势
- Manufactured and tested in DIN EN ISO 9001:2008 accredited laboratory
- The solution is pre-diluted to a concentration that falls into the range of our Spectroquant® test kits. This eliminates the need for dilution prior to analysis and hence avoids a common source of error
- Ready-to-use diluted reference materials (RMs) along with expanded measurement uncertainty ensure absolute precision
- Accompanied with a certificate of analysis (COA) detailing the certified values, including uncertainty and expiry date
- Directly traceable to standard reference materials (SRM) from the National Institute of Standards and Technology (NIST) or to United States Pharmacopeia (USP)
- Reliable and reproducible results

饮用水检测技术包括定量检测、色谱法、分光光度法、反射法、物理参数测定（如浊点、颜色、硬度、pH、气味）和病原体检测（分子或细胞培养法）。这些质量控制试验既要在工艺过滤（絮凝和澄清等）后的输入水源中进行，也要在过滤后的输出用水中进行（如水龙头取样）。
