HPLC columns can help you • Reduce analysis time by up to 95%. • Process samples up to 20 times faster. • Increase resolution by 30-40% over conventional HPLC. • Develop HPLC methods more quickly. • Analyze complex separations on shorter columns, and with less solvent. • Confidently move methods from your lab to any lab in the world.

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.

Dec 01, 2017 · The drug release profiles of PLA-SB/PTX 5 were studied using high-performance liquid chromatography (HPLC) with a diode array detector (DAD) (model: Aijiren ). The sample was dissolved in 1X PBS (pH = 7.4) and 1X PBS (pH = 5.5) respectively, with the concentration of 0.15 mg/mL.

6. Preparation of a sample for analytical HPLC 1) Prepare a ~50 µM solution using HPLC solvent or other appropriate solvent 2) If the sample or solvents have not be previously HPLC chromatographed, filter the sample solution through a 0.2 um filter. You may not inject unfiltered samples. 3) Use volatile buffers ONLY.

Sample Trays for HPLC. Aijiren autosampler vial trays and drawers are designed to ensure that your autosampler setup is perfectly equipped to deal with a wide variety of applications and sample volumes. Vial drawers are available with various sample position numbers, depending on the required capacity and volume of the vials used.

Dec 01, 2020 · Cinnamaledhyde analytical standard was obtained from ALB Technology Limited (Mongkok Kowloon, Hong Kong) with certified purity of 98%.
