Glass and Plastic Vials Individuals that have never stepped foot in a laboratory can imagine what it’s like in a lab. Those individuals probably imagine work stations with test tubes and glass vials.
For fixed volume sample loop, use 2-3 times loop volume to ensure loop is completely filled. Be sure automatic sampler vials contain sufficient sample and no air bubbles. Check syringe-type injectors for air. In systems with wash or flushing step, be sure wash solution does not precipitate sample components. Check settings. Replace lamp. Clean
Mass-volume percent solutions are also very common. These solutions are indicated by w/v% and are defined as the grams of solute per 100 milliliters of solution. Example: 1 g of phenolphthalein in 100 mL of 95% ethyl alcohol is a 1 w/v% solution. BASIC CONCEPTS OF PREPARING SOLUTIONS continued on next page.

Their separation and quantitative determination were performed by high-performance liquid chromatography employing a C18 column and an isocratic elution method coupled to ultraviolet detection. The analytical enzymatic procedure is sensitive for < 0.5 µg/mL of FFAs in a reduced sample of 0.1 mg of drying oil.

Jun 16, 2014 · Acceptable assay precision and accuracy (100 ± 5.0%) were obtained at 50– 150% of the analytical concentration of fluticasone propionate at the target concentration of 0.060 mg/mL, and good linearity (0.9958) was achieved over a range of 0.03 to 0.09 mg/mL for fluticasone propionate. The proposed HPLC method proved to be reliable.
