Product Overview
This Lead 1000 ppm ICP-ML single-element standard is a high-purity liquid solution formulated for precise calibration in inductively coupled plasma mass spectrometry (ICP-MS) and optical emission spectroscopy (ICP-OES). The standard is prepared using ultra-pure lead salts dissolved in high-quality nitric acid, ensuring minimal matrix interference and maximum stability. Each batch undergoes rigorous quality control to guarantee accuracy within ±1% of the stated concentration, with traceability to NIST or equivalent reference materials. The solution is packaged in HDPE bottles to prevent contamination and ensure long-term stability. Its low background impurity profile makes it ideal for trace-level lead analysis in environmental, food safety, and industrial testing applications. The 100 ml pack size offers sufficient volume for routine calibration while minimizing waste. Compatible with most ICP instruments, this standard eliminates the need for in-house dilution preparation, saving time and reducing errors in analytical workflows.
FAQs
1. What is the shelf life of this Lead 1000 ppm ICP-ML standard?
The standard remains stable for 24 months from the date of manufacture when stored unopened at room temperature (15-25°C). Once opened, use within 6 months for optimal accuracy.
2. Can this standard be used for both ICP-MS and ICP-OES calibration?
Yes, the 1000 ppm concentration is suitable for both ICP-MS and ICP-OES instruments, though you may need to dilute it further for ICP-MS applications depending on your instrument’s sensitivity requirements.
3. What acid matrix is used in this Lead standard solution?
The solution is prepared in a 2% nitric acid matrix, which is standard for ICP applications and ensures complete lead solubility without precipitation.
4. Is this standard traceable to any international reference materials?
Yes, the concentration is traceable to NIST or equivalent primary standards, with certification documentation provided for each batch.
5. What precautions should be taken when handling this standard?
Always wear appropriate PPE including nitrile gloves and safety goggles. Handle in a fume hood to avoid inhalation of acid vapors, and rinse any spills immediately with copious amounts of water.
