General description

EMPARTA solvents are designed for routine chemical synthesis, drying, purification, and critical labware cleaning in quality control environments. Engineered for precision, they deliver consistently reproducible results essential for rigorous validation and documentation.

Exceptional Quality Standards: These solvents meet or exceed ACS specifications, providing assurance of high quality that is crucial for accurate testing and analysis in quality control.

Consistent Reproducibility: Designed for precision, the solvents ensure that results can be reliably reproduced, which is vital for maintaining compliance and integrity in quality control processes.

Versatile Applications: Suitable for a variety of QC tasks, including analytical testing, method validation, and testing USP/NF monographs, these solvents support a comprehensive approach to quality assurance in laboratory settings.

Application


  • Environmental sampling of volatile organic compounds during the 2018 Camp Fire in Northern California.: This study analyzed volatile organic compounds, including o-Xylene, sampled during the 2018 Camp Fire in Northern California, highlighting the analytical methods used to assess environmental exposure and chemical composition in wildfire scenarios (Simms et al., 2021).

  • Urinary BTEX, MTBE and naphthalene as biomarkers to gain environmental exposure profiles of the general population.: Focuses on the use of urinary biomarkers, such as BTEX (including o-Xylene), for assessing environmental exposure in populations, demonstrating the integration of analytical chemistry techniques in epidemiological studies (Fustinoni et al., 2010).

  • Genotoxic effects of volatile organic compounds in a chemical factory as evaluated by the Tradescantia micronucleus assay and by chemical analysis.: Investigates the genotoxic effects of VOCs, including o-Xylene, in a chemical plant environment, using both biological assays and chemical analysis to evaluate risk and exposure (Kim et al., 2003).

  • Time-gated pulsed glow discharge: real-time chemical speciation at the elemental, structural, and molecular level for gas chromatography time-of-flight mass spectrometry.: This paper presents a novel analytical technique for real-time chemical speciation, useful in analyzing compounds like o-Xylene, providing insights into complex analytical methodologies in chemistry (Lewis et al., 2003).
