Fused Silica Capillary
midpolarity Crossbond phase Excellent inertness and selectivity for active environmental compounds, such as PAHs. Low bleed for use with sensitive detectors, such as MS. 340/360 °C upper temperature limits. Equivalent to USP phase G3. highly polar phase; biscyanopropyl polysiloxane —not bonded Stationary phase selectivity optimized for isomer separation to ensure accurate quantification of critical / cis FAMEs. trans Application-specific QC test guarantees consistent, reliable performance for AOAC 996.06 and AOCS Ce 1j-07 methods. Excellent sample capacity; no peak distortion means easy, accurate peak integration. Temperature range: 20–250 °C. midpolarity proprietary phase Ideal for EFSA PAH4 analysis —separates all priority compounds: benz[a]anthracene, chrysene, benzo[b]fluoranthene, and benzo[a]pyrene. Best resolution of chrysene from interfering PAHs, triphenylene, and cyclopenta[cd]pyrene. Complete separation of benzo [b], [k], [ j], and [a] fluoranthenes. 360 °C thermal stability allows analysis of low-volatility dibenzo pyrenes. midpolarity Crossbond phase Highest thermal stability in the industry ensures dependable, accurate MS results and increased uptime. Stabilized cyano phase selectivity improves the performance of existing methods. Ideal for solvents, glycols, and other polar compounds. Rigorous QC testing ensures inertness and accurate, reliable data for multiple compound classes. Maximum temperature: 320 °C. polar phase; Crossbond polyethylene glycol Application-specific columns for FAMEs, specially tested with a FAME mixture. Temperature range: 20 °C to 250 °C. nonpolar phase; dimethyl polysiloxane Columns processed for high-temperature applications, such as high molecular weight hydrocarbons. Temperature range: -60 to 400 °C. High-polarity, stable polyethylene glycol (PEG) stationary phase.
