Our 2 mL polypropylene vials (in outer size) and asscoiated screw caps, crimp caps or even snap caps are the perfect fit for HPLC and GC instrument platforms across a wide variety of applications, including pharmaceutical, environmental, energy and fuels, forensics, materials science, biopharmaceutical, proteomics, and metabolomics.
HPLC runs were performed using Aijiren HPLC system equipped with a Phenomenex Rezex ROA (300 x 7.8 mm) column. Sulfuric acid (0.25 mM) in water was used as an eluent at 40 °C with a flow rate 0.35 ml/min. HMF was detected using UV-detector, whereas fructose and glucose were analyzed using refractive index (RID) detector.
