Product Overview
This Phosphorus 1000 ppm ICP-ML single-element standard is engineered for high-precision trace analysis in inductively coupled plasma (ICP) spectroscopy. Formulated in a matrix-matched solution, it ensures minimal interference and maximum accuracy for phosphorus detection across environmental, food, and industrial testing applications. The standard is prepared using ultra-pure reagents and undergoes rigorous quality control to guarantee consistency between batches. Its stability is validated for long-term storage, reducing the need for frequent recalibration. The NIST-traceable certification provides documented accuracy, making it ideal for laboratories requiring compliance with ISO 17025 or GLP standards. The liquid form allows for easy dilution and integration into automated sample preparation workflows. Compatible with most ICP-OES and ICP-MS instruments, this standard eliminates matrix effects that can skew results in complex samples. The 100 ml packaging balances cost-efficiency with sufficient volume for routine laboratory use, while the amber bottle protects against photodegradation.
FAQs
1. What is the shelf life of this Phosphorus ICP standard when stored properly?
The standard remains stable for 24 months from the date of manufacture when stored unopened at room temperature in its original packaging. Once opened, use within 6 months for optimal accuracy.
2. Can this standard be used for both ICP-OES and ICP-MS applications?
Yes, the 1000 ppm concentration is suitable for both techniques, though you may need to dilute it further for ICP-MS to avoid detector saturation with high phosphorus concentrations.
3. What diluent is recommended for preparing working standards from this solution?
Use 2% nitric acid (HNO₃) prepared from trace-metal-grade acid and deionized water (18.2 MΩ·cm) to maintain matrix compatibility and prevent contamination.
4. How does this standard compare to multi-element phosphorus standards?
Single-element standards like this offer higher purity for phosphorus-specific analysis, eliminating potential interferences from other elements present in multi-element mixes. They’re ideal when phosphorus is your sole analyte of interest.
5. Is this standard compatible with automated liquid handling systems?
The solution’s viscosity and lack of particulate matter make it fully compatible with most automated diluters and liquid handlers, though we recommend verifying with your specific instrument’s requirements.
