Product Overview
This PAH Mix 3 (EPA 610 standard) is a certified reference material designed for precise environmental analysis and calibration of gas chromatography-mass spectrometry (GC/MS) systems. The mixture contains 16 priority polycyclic aromatic hydrocarbons (PAHs) at defined concentrations, ensuring accuracy in quantitative analysis. Each component is dissolved in high-purity methanol, providing stability and consistency for reliable lab results. The formulation adheres strictly to EPA Method 610 specifications, making it ideal for regulatory compliance testing. With traceability to NIST standards, this reference material guarantees reproducibility across experiments. Its low impurity profile minimizes interference, while the sealed ampoule packaging prevents contamination. Whether used for method validation, instrument calibration, or quality control, this PAH mix delivers exceptional performance with long-term stability when stored properly at 2-8°C.
FAQs
1. What is the concentration range of individual PAHs in this EPA 610 mix?
The mix contains 16 PAHs at concentrations typically ranging from 100 to 200 µg/mL in methanol, with exact values provided in the certificate of analysis.
2. Can this PAH mix be used with HPLC instead of GC/MS?
While optimized for GC/MS analysis, it can be adapted for HPLC with appropriate method modifications, though sensitivity may vary.
3. What is the shelf life of this reference material?
When stored unopened at 2-8°C, the mix maintains stability for 24 months from the date of manufacture.
4. Are there any special handling precautions for this methanol-based solution?
Standard lab safety measures for methanol should be followed, including use in a fume hood and proper PPE.
5. How does this compare to EPA 525 or 8270 PAH mixes?
EPA 610 focuses specifically on 16 priority PAHs, while 525/8270 include additional semivolatile compounds and different concentration ranges.
