Collection: n-Paraffins [GC Standards]
n-Paraffins [GC Standards] — contains standard mixtures of n-paraffins (straight-chain alkanes) with specific carbon number ranges, from C7 to C25, prepared at standard concentrations and solvents for gas chromatography. Each mixture includes several consecutive homologs, making it easier to determine retention indices in GC analysis.
These n-paraffin standard mixtures are used for retention time calibration and Kovats retention index calculation in gas chromatography analysis, for example identification of volatile compounds in essential oil samples, petroleum products, or residue analysis. Testing laboratories and quality control departments use this C7 to C25 series to verify column performance and support component identification based on n-alkane elution patterns.
Example products in this collection: TCI S0457 Standard Mixture of n-Paraffins (consists of C21, C22, C23, C24 and C25) [Standard Material for GC], TCI S0277 109-66-0 Pentane [Standard Material for GC], TCI S0456 Standard Mixture of n-Paraffins (consists of C17, C18, C19 and C20) [Standard Material for GC], TCI S0278 110-54-3 Hexane [Standard Material for GC], TCI S0455 Standard Mixture of n-Paraffins (consists of C12, C13, C14, C15 and C16) [Standard Material for GC], TCI S0279 142-82-5 Heptane [Standard Material for GC], TCI S0454 Standard Mixture of n-Paraffins (consists of C7, C8, C9, C10 and C11) [Standard Material for GC], TCI S0280 111-65-9 n-Octane [Standard Material for GC].
Pay attention to the carbon number range suitable for the analyzed sample, the type of carrier solvent, and the concentration of each component in the standard mixture so that retention index calibration results are accurate. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
