Acetone ≥99.8%, SupraSolv® for GC-MS, distilled, Supelco®

Supplier: MilliporeSigma

SupraSolv® MS is dedicated for use in gas chromatography coupled with mass spectrometric detection. SupraSolv® solvents offer the largest specified retention time range, a clear baseline and a minimal signal-to-noise ratio leading to reliable and reproducible analysis results. This method is used e. g. for the analysis of dioxins and furans (PCDD/PCDF) in food and water samples or for the determination of PAH (polycyclic aromatic hydrocarbons) in food.

Supplier: MilliporeSigma

SupraSolv® ECD and FID is specially developed for gas chromatography in combination with ECD (Electron Capture Detetor) and FID (Flame Ionization detector). SupraSolv® solvents offer the largest specified retention time range, a clear baseline and a minimal signal-to-noise ratio leading to reliable and reproducible analysis results. Typical applications include the determination of polychlorinated biphenyls (PCB) in water and soil or pesticides in fruits and vegetables. Also ideal for many EPA protocols.

Acetone ≥99.9% (dried basis), GC2™ for gas chromatography, for pesticide residue analysis, Burdick & Jackson™

Supplier: Honeywell Research Chemicals

B&J GC2 Solvents are developed for trace analysis at or below the part-per-billion level, using capillary gas chromatography. Each lot is performance tested to meet demanding GC specifications.

Samples of every B&J GC2 solvent are concentrated 1000-fold and tested by temperature-programmed capillary GC-FID. This analysis detects both low-boiling and high-boiling molecules, anything eluting from toluene through diesel fuel and other semi-volatile compounds of environmental interest.

Features:
Less than 1 ppb trace contamination for semi-volatiles with a molecular weight greater than toluene (92).
Ideal for EPA protocols
Actual lot chromatograms available upon request

Electron capture GC: No residue peaks greater than two ng/L as lindane.

Flame ionization GC: No peaks greater than one ng/mL, having a retention time of greater than diacetone alcohol, on a crossbonded 5% diphenyl/95% dimethyl polysiloxane capillary column for a splitless injection of a 1000-fold sample concentrate after exchange into hexane.
