Import Tips
• Include NIST-traceable certificate of analysis specifying concentration and stability data
• Label as 'certified reference material for instrumental calibration only' to avoid reagent confusion
• Monitor for reclassification under Montreal Protocol restrictions on ozone-depleting substances
