Product Overview
This 1000 ppm Holmium single-element standard is formulated specifically for inductively coupled plasma mass spectrometry (ICP-MS) and optical emission spectroscopy (ICP-OES) applications, offering exceptional purity and stability in a 2% nitric acid matrix. The standard undergoes rigorous quality control to ensure lot-to-lot consistency, with concentrations traceable to NIST reference materials for reliable analytical results. The nitric acid matrix minimizes potential interferences while maintaining element stability over extended periods, making it suitable for both routine laboratory use and high-sensitivity research applications. Packaged in high-density polyethylene (HDPE) bottles to prevent contamination, this standard maintains its integrity during storage and handling. The concentration is certified through multi-point calibration using primary standards, with uncertainty values provided for complete analytical transparency. Compatible with most ICP instrumentation, this Holmium standard delivers consistent performance across various sample matrices without requiring complex preparation procedures.
FAQs
1. What is the shelf life of this Holmium standard when stored properly?
When stored unopened at room temperature in its original container, this standard maintains its certified concentration for 24 months from the date of manufacture. Once opened, we recommend using within 12 months for optimal accuracy.
2. Can this standard be used for both ICP-MS and ICP-OES applications?
Yes, the 1000 ppm concentration and nitric acid matrix make it suitable for both ICP-MS and ICP-OES instrumentation, though you may need to prepare working standards through appropriate dilution for optimal sensitivity in your specific application.
3. What materials are used for the bottle and cap to prevent contamination?
The standard is packaged in high-density polyethylene (HDPE) bottles with polypropylene caps, both of which are acid-washed and tested for trace metal contamination to ensure sample integrity.
4. How should I prepare working standards from this 1000 ppm solution?
For most applications, we recommend serial dilution using 2% nitric acid as the diluent to maintain matrix consistency. Typical working ranges are 1-100 ppb for ICP-MS and 10-500 ppb for ICP-OES, though optimal concentrations depend on your instrument sensitivity.
5. What certification documentation is provided with this standard?
Each bottle includes a certificate of analysis detailing the certified concentration, uncertainty values, traceability information, expiration date, and storage recommendations, along with batch-specific quality control data.
