Researchers can now take advantage of enhancements to ultrapure methylene chloride solvents that deliver an interference-free baseline in chromatograms for better detection of trace levels of target analytes in identifying compounds of interest. This is particularly important for environmental testing of polycyclic aromatic hydrocarbons (PAHs), as well as pesticides in food, water, and soil samples.

Fisher Chemical Optima and GC Resolv Methylene Chloride solutions are designed specifically for customers using methylene chloride in pharmaceutical, environmental, food and chemical industries applications. These solutions can be used as an extraction solvent for identifying and quantifying by gas chromatography (GC-MS, GC-FID, and GC-ECD) trace amounts of volatile organic compounds.
“Instrumentation advances are leading to lower analyte detection limits,” said Stephen Roemer, global director, R&D, Fisher Chemical, Thermo Fisher Scientific. “With our new Optima and GC Resolv solutions, we implemented a quality by design (QbD) approach to manufacture ultrapure methylene chloride in order to provide researchers with an extraction solvent that consistently shows an interference-free baseline during GC analysis."
The enhanced grades of methylene chloride ensure a high-quality solvent from time of manufacturing to when the analyst first opens the container. Extended shelf life studies confirm that solvent quality is sustained even in large-volume returnable containers, such as FisherPak. Additional enhancements include:
- High purity: raw material screening, optimized distillation processes and packaging innovations provide extremely clean product for critical GC applications.
- Lot-to-lot consistency: a QbD (Quality by Design) approach to manufacturing, coupled with stringent quality control procedures, ensures product quality in every bottle.
- Outstanding performance: interference-free baseline during trace analysis of standards on gas chromatography instruments with various detectors (GC-MS, GC-FID and GC-ECD) at 1000-fold concentration.
