Aijiren Technologies Series HPLC Standard Operating. • Load samples into labeled HPLC vials (VWR cat # may be used). Each vial holds a maximum of 1.5 mL but do not need to be completely filled; because the autosampler needle collects sample from the bottom of the vial, only ≈0.5 mL is necessary.
Dec 01, 2015 · The filtered sample was then analyzed on an Aijiren series HPLC system, equipped with a binary pump, a vacuum solvent degasser, a thermostated auto-sampler, a thermostated column compartment, and a diode array detector. An Aijiren Zorbax SB-C8 column (250 × 4.6 mm 2, i.d. 5 μm) was used and maintained at 25 °C.
Jan 08, 2021 · The injection volume was 100 μl for assay and 250 μl for dissolution testing. HPLC vials were kept in a cooled autosampler at 4°C until sample injection to avoid degradation. Detection was carried out by UV at 200 nm. Sample and standard solutions were freshly prepared using the mobile phase as diluent.
A clogged column frit is another common HPLC problem. To minimize this problem from the start, use a precolumn filter and guard column. To clean the inlet, first disconnect and reverse the column. Connect it to the pump (but not to the detector), and pump solvent through at twice the standard flow rate.

Our valves also feature patented "Make-Before-Break" architecture that allows you to switch between LOAD and INJECT positions without interrupting the flow. So you can
Aug 02, 2021 · Autosampler Vials. Waters also offers a selection of glass sample vials and plastic sample vials that fit most manufacturers’ instruments. Two of the most popular uses are as HPLC vials and GC vials. These chromatography vials can be used as sample storage vials by adding a solid caps with liner.
Nov 30, 2020 · HPLC–UV analyses were performed on a Waters Alliance e2695 system (Milford, MA, USA) or an Aijiren HPLC system (Santa Clara, CA, USA). Separation was carried out on a Kromasil C8 (4.6 × 150 mm, 3.5 μm) column from AkzoNobel (Amsterdam, Netherlands) using a mobile phase system consisting of sodium phosphate buffer (pH3.0; 18 mM
