甲醇中10种硝基苯类混标

Nitrobenzenes Mix

Catalog Number：Q-7352-O

Solvent：Methanol

Hazards：Iritant, Flammable

Packaging，Storage，Instructions For Use

This standard is packaged in a flame-sealed ampule and must be stored at 2°C to 8°C. To use this standard, allow it to reach room temperature. Mix it gently by inversion. Inspect for precipitate. If present, sonicate for a few minutes to redissolve. Open the ampule and withdraw an aliquot appropriate for your application.

Traceability Information

Analyte Source Materials：The highest purity analyte source materials are used in the manufacture of this standard. The actual purity is referenced above.

Method： This standard was verified Volumetrically/Gravimetrically.

Balance：AlI analytical balances are calibrated on a semiannual basis by an ISO 17025 accredited calibration laboratory and are traceable to NIST. Traceable Calibration Certificate available upon request.

All balances are checked daily by an in-house standard operating procedure. The weights used for this daily verification are calibrated annually by an ISO 17025 accredited calibration laboratory and are certified traceable to NIST. Certificate of Calibration and Traceability available upon request.

Thermometer：All thermometers are NIST traceable through thermometers that are calibrated annually by an ISO 17025 accredited calibration laboratory.

Glassware：All glassware used in the manufacture of our reference materials is Class A. An in-house standard operating procedure is used to verify all glassware prior to it being placed into service. Volumetric pipetors are calibrated every four months by an ISO 17025 accredited calibration laboratory.
