SupraSolv\u00ae and SupraSolv\u00ae hypergrade solvents are optimized for high reliability in trace-level GC applications such as pesticide, dioxin, oil index, and residue analysis. Discover how these solvents provide highly reproducible, low-noise chromatographic performance for your analytical challenges.<\/p>\n<h2>Why Experts Choose SupraSolv\u00ae High Purity Solvents for Gas Chromatography<\/h2>\n<ul>\n<li>Analytical reliability you can trust: Very high purity with a minimal signal-to-noise ratio delivers reproducible baselines for confident decision making.<\/li>\n<li>Widest application coverage: A broader retention time window, during which specified contaminants are lowest, than conventional GC solvents. This breadth supports gas chromatography applications, including highly sensitive pesticide and dioxin analyses.<\/li>\n<li>Exceptional batch-to-batch consistency: Every batch is tested to the same high standards. This reduces variability and helps minimize repeat analyses.<\/li>\n<li>Efficiency gains in routine workflows: Stable background and minimized blank interference reduce troubleshooting time and solvent-related revalidation work.<\/li>\n<li>Developed for sensitive detection: Specifically designed for residue and environmental analysis. Purity and suitability are secured by special distillation cuts and verification using a variety of detectors.<\/li>\n<li>Application-oriented confidence across workflows: Comprehensive quality information and suitability testing provide the reliability, accuracy, and analytical safety laboratories require.<\/li>\n<li>SupraSolv\u00ae hypergrade for the highest demands: Even larger specified retention time ranges and lower permissible interference signals within that range. Recommended wherever analytical results must meet high levels of reliability.<\/li>\n<\/ul>\n<p>Together, these advantages explain why laboratories choose SupraSolv\u00ae High Purity Solvents for Gas Chromatography when reliability, consistency, and efficiency are essential.<\/p>\n<p>\u00a0<\/p>\n<h2>GC Detector Compatibility &amp; Technical Overview<\/h2>\n<ul>\n<li><strong>State-of-the-art purification and recovery<\/strong>: SupraSolv\u00ae solvents are recovered during special distillation cuts and produced using the latest manufacturing processes. This supports suitability for gas chromatography.<\/li>\n<li><strong>Application-tailored specifications<\/strong>: Each solvent quality is defined with individual specifications that are tailored to its specific area of application. This includes detector-specific retention time windows and limits for interference signals within those windows.<\/li>\n<li><strong>Detector-specific development and testing (ECD\/FID)<\/strong>: SupraSolv\u00ae ECD and FID solvents are developed and tested specifically for Electron Capture Detector and Flame Ionization Detector use. This provides a clear baseline and minimal signal-to-noise ratio within a specified retention time range. Specification examples:\n<ul>\n<li>GC-ECD: retention range 1,2,4-Trichlorobenzene to Decachlorobiphenyl (Lindane standard); individual signals \u2264 3 pg\/mL.<\/li>\n<li>GC-FID: retention range n-Undecane to n-Tetracontane (n-Tetradecane standard); individual signals \u2264 3 ng\/mL.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Dedicated MS grade with defined scan range<\/strong>: SupraSolv\u00ae MS solvents are dedicated for GC coupled with mass spectrometric detection and specified for:\n<ul>\n<li>GC\u2013MS: retention range n-Undecane to n-Tetracontane; scanning area 30 to 600 amu; individual signals \u2264 3 ng\/mL.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Headspace-grade solvents with ICH-based purity window<\/strong>: SupraSolv\u00ae headspace solvents are designed for residual solvent analysis according to ICH, Ph. Eur. and USP, with a defined purity window for all ICH classes and batch-wise headspace application testing:\n<ul>\n<li>Every class 1 residual solvent \u2264 1 \u00b5g\/g.<\/li>\n<li>Every class 2 residual solvent \u2264 10 \u00b5g\/g.<\/li>\n<li>Every class 3 residual solvent \u2264 50 \u00b5g\/g.<\/li>\n<\/ul>\n<p>These products were developed in close cooperation with an experienced headspace laboratory and manufactured using special production processes.<\/p>\n<\/li>\n<li><strong>Broader retention windows with SupraSolv\u00ae hypergrade<\/strong>: SupraSolv\u00ae hypergrade offers a larger specified retention time range and lower permissible concentrations of interference signals within the retention time range than SupraSolv\u00ae grade. This enables detection across low- and higher-boiling regions. Hypergrade specifications cover GC-ECD, GC-FID and GC\u2013MS:\n<ul>\n<li>GC-ECD (Dichloromethane to 1,2,4-Trichlorobenzene; Tetrachloromethane standard): \u2264 1 ng\/mL.<\/li>\n<li>GC-ECD (1,2,4-Trichlorobenzene to Decachlorobiphenyl; Lindane standard): \u2264 2 pg\/mL.<\/li>\n<li>GC-FID (n-Undecane to n-Tetracontane; n-Tetradecane standard): \u2264 2 ng\/mL.<\/li>\n<li>GC\u2013MS (n-Undecane to n-Tetracontane; 30 to 600 amu): \u2264 2 ng\/mL.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Comprehensive detector compatibility across methods<\/strong>: The portfolio spans GC-FID, GC-ECD, GC\u2013MS and HS-GC, with grades designed and verified for each technique. This supports use from residue and environmental analysis to trace-level determinations.<\/li>\n<li><strong>Method-aligned retention coverage<\/strong>: For classical pesticide analysis (EPA Method 508, GC-ECD), the specified ECD retention time range of SupraSolv\u00ae ECD and FID covers all analytes of interest for this application.<\/li>\n<li><strong>Batch-level quality control<\/strong>: Every batch is tested to the same high standards. Suitability testing involves a variety of detectors and highly concentrated solvents. SupraSolv\u00ae headspace solvents additionally undergo a headspace application test on each batch.<\/li>\n<li><strong>Packaging and dispensing systems designed to protect purity<\/strong>: High-grade glass bottles and stainless steel returnable barrels are paired with specially designed withdrawal systems. Solvents, packaging and dispensing systems are optimally matched to prevent detectable contamination and support reliable, safe dispensing.<\/li>\n<li><strong>Retention time window engineering<\/strong>: SupraSolv\u00ae solvents are specified for low contaminant levels within defined retention time windows that are broader than conventional GC solvents.
