Supplied with an attached 8-425 black phenolic screw cap with a 14B white rubber liner for use with aqueous samples. Lab File™ sample vials are packaged in corrugated trays with partitions and then shrink-wrapped to
Complete solution for derivatization. The system includes the Aijiren Tech Reacti-Therm heating/stirring module for uniform dry heating of samples, which you can couple with the Reacti-Vap evaporator for simultaneous or separate delivery of pressurized gas. Modular design: switch aluminum blocks and vials; attach compatible evaporator
Aijiren's 2 mL screw top vials are constructed from Type 1 borosilicate glass, with low metal content, to protect your sample from destabilizing or leaching. Our 2 mL glass vials are available in both amber and clear versions. The associated 9 mm vial screw cap comes with your choice of septa constructed from either PTFE/silicone, PTFE/silicone

This can either be done as a bulk volume addition or integrated into the derivatization step. Substitute the required amount of borate buffer with NaOH to neutralize the HCl in the sample. In the derivatization reaction vial mix, place 10 µL of xM NaOH and 60 µL of borate. Add 10 µL of the AA sample (in xN HCl). Derivatize with 20 µL of
including sample dilution and reagent addition. For this study, we set the system to automatically mix the sample and derivatization reagents in the autosampler needle. O-phthalaldehyde (OPA) and 9-fluorenylmethyl chloroformate (FMOC) are well-known derivatization reagents that can react rapidly with amino acids at room temperature. Therefore, pre-

preparation vial. After 60 s, stop the derivatization reaction by mixing with injection diluent. Add this injection diluent to decrease the pH of the derivatization mixture prior to injection for enhanced column lifetime. The successful neutralization of the basic derivatization mixture by adding the injection diluent can be checked in preliminary

as the check sample to evaluate accuracy during the initial method validation. Pre-column derivatization A 4 mg portion of the AQC reagent in a 2 mL amber glass screw-top vial was solubilized by adding 1 mL anhydrous acetonitrile and alternately vortexing and heating to 80 °C in a heat block for a few minutes until dissolved.

Jul 1, 2016 · In the derivatization method FAME, this solution was treated with TMAH according to the derivatization protocol described below. Methyl Ester Derivatization of Isolated FFA Using TMAH as a Catalyst. The FFA extract (300 μL) was transferred into a PTFE/white silicone capped 2-mL amber GC vial (Aijiren Technologies Ireland Ltd.).
Aug 29, 2023 · Common Methods of Derivatization. Gas Chromatography. Derivatization is generally necessary in the analysis by GC of compounds that exhibit low volatility, have poor thermal stability, contain “active” groups that can lead to loss of sample to intermolecular hydrogen bonding or adsorption on the inlet or column, and/or demonstrate poor sensitivity at the detector.
