SLB-5ms Capillary GC Column

Sigma-Aldrich Supelco

SLB-5ms Capillary GC Column Application: The 5% phenyl equivalent phase provides a boiling point elution order with a slight increase in selectivity, especially for aromatic compounds. The low bleed characteristics, inertness, and durable nature make it the column of choice for environmental analytes (such as semivolatiles, pesticides, PCBs, and herbicides) or anywhere a low bleed non-polar column is required. USP Code: This column meets USP G27 and G36 requirements. Phase: Bonded and highly crosslinked; silphenylene polymer virtually equivalent in polarity to poly(5% diphenyl/95% dimethyl siloxane) Temp. Limits: ≤0.32 mm I.D.: -60 °C to 340 °C (isothermal) or 360 °C (programmed) Temp. Limits: ≥0.53 mm I.D.: -60 °C to 330 °C (isothermal) or 340 °C (programmed)

Solid-Phase ExtractionSolid-phase extraction (SPE) is used for clean-up, extraction and concentration of semi-volatile or non-volatile analytes from complex mixtures including blood, urine and food samples. Multiple formats are available for conducting SPE, including prepacked SPE cartridges, disks and microplates, as well as SPE sorbent powders for manual packing. SPE systems can be used to automate the process and extract multiple samples at once. Solid-phase microextraction (SPME) and supported liquid extraction (SLE) products are also available in the same formats. Find the best SPE, SLE and SPME equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.GC-MS GC-MS (gas chromatography-mass spectrometry) instruments and equipment are used to separate, quantify and identify mixtures of small and volatile compounds, such as polycyclic aromatics, fatty acids and alcohols. Often used in drug detection, forensic investigation and environmental analysis for pesticides and contaminants, GC-MS is a powerful addition to your lab’s analytical capabilities. GC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzers can give greater sensitivity and resolution to your analysis.
