Product Overview
This Yttrium 10 ppm ICP-ML single-element standard is a high-purity, matrix-matched solution designed for precise elemental quantification in inductively coupled plasma (ICP) spectroscopy. Formulated in a 2-5% nitric acid matrix, it ensures long-term stability and minimal interference during analysis. The standard is traceable to NIST SRM or equivalent reference materials, guaranteeing accuracy for calibration curves, method validation, and routine quality control in analytical laboratories. Its low concentration (10 ppm) is ideal for detecting trace levels of Yttrium in environmental, geological, or industrial samples without requiring additional dilution. The solution is filtered through 0.2 µm membranes to eliminate particulate contamination, and the amber HDPE bottle with tamper-evident seal prevents photodegradation and external contamination. Compatible with most ICP-OES and ICP-MS instruments, this standard eliminates matrix effects that can skew results in complex sample types. Store at 15–25°C in the original container to maintain integrity; avoid freezing or exposure to direct sunlight. Each batch undergoes multi-point verification for concentration accuracy, with certificates of analysis provided for regulatory compliance. The 100 ml pack size balances cost-efficiency with sufficient volume for repeated calibrations, reducing the need for frequent replenishment in high-throughput labs.
FAQs
1. What is the shelf life of this Yttrium ICP standard when unopened?
The unopened standard remains stable for 24 months from the date of manufacture when stored at 15–25°C in its original packaging. Always check the certificate of analysis for batch-specific expiry details.
2. Can this standard be used directly for ICP-MS without further dilution?
Yes, the 10 ppm concentration is suitable for direct use in most ICP-MS applications targeting trace-level Yttrium detection. However, for ultra-trace analysis (< ppb), further dilution with high-purity acids may be required to match instrument sensitivity.
3. Is this standard compatible with organic solvents like methanol or acetone?
No, this aqueous standard is stabilized in nitric acid and should not be mixed with organic solvents, as it may cause precipitation or instability. For organic matrices, consider a solvent-compatible standard or consult the instrument manufacturer’s guidelines.
4. How should I dispose of unused or expired Yttrium standard?
Follow local hazardous waste regulations for disposal. Neutralize small quantities with a base (e.g., sodium hydroxide) before disposal, or contact a licensed chemical waste handler for larger volumes. Never pour down drains or discard with general waste.
5. Does this standard require refrigeration after opening?
Refrigeration is not mandatory, but storing the opened bottle at 4°C can extend stability, especially in humid environments. Ensure the cap is tightly sealed to prevent evaporation or contamination. Avoid freezing, as it may alter the matrix composition.
