Sample Preparation Flour was purchased in a supermarket in Shanghai, People’s Republic of China. Add 10 mL of DMF/DMSO (9:1, v/v) to 5 g of flour in a 20 mL centrifuge tube. Mix for 10 min to extract, then centrifuge for 10 min at 4000 rpm. Prior to injection, filter the supernatant through a 0.45 µm filter.6

3 mL luer-lock syringe (P/N S7510-3) and filtered through a Target2 45 µm syringe filter (P/N F2500-7) into an HPLC vial before the sample was submitted for LC/MS analysis. Pesticide stock solution A stock solution was created from all individual pesticide vials and labeled Solution K = 1 ppm final concentration.

For larger volume samples up to 125 mL, the 25 mm Acrodisc syringe filter is the preferred choice and is available with a pre-filter for difficult or dirty samples. Benefits include: Available in 0.2 μm and 0.45 μm pore sizes for UHPLC and HPLC applications.

Less. Steritop bottle top filter units provide a large filter area for rapid sterile filtration of aqueous fluids into narrow-mouth (33 mm) or wide-mouth (45 mm) bottles. A small tab inside the funnel secures an optional prefilter in-place during filtration. For added protection against contamination, the threads for bottle attachment have been

Oct 19, 2020 · Some of the most common types of filters include syringe filters, centrifuge filters, and filter vials. Syringe Filters Chromatography syringe filters are one time use cartridges attached at the end of a syringe that trap particulates from a liquid sample before analysis. These filters are commonly used for HPLC and ion chromatography.

With low extractables and low analyte-binding membranes, Millex® syringe filters are the most convenient, highest-quality syringe filters for sensitive instrumental analyses, including gas, liquid, and ion chromatography. Wide chemical compatibility enables their use with virtually any sample composition. Request your FREE Millex® filter sample!

SPARTAN syringe filters with 0.2 and 0.45 µm pore sizes, 25 mm diameter Whatman GD/X™ syringe filters with 0.2 µm pore size, and Mini-UniPrep™ syringeless filters with 0.2 µm pore size. Bovine serum albumin (BSA) was selected as the typical protein. A 5 mg/mL stock was

Syringe filters with different pore size ratings are suitable for different applications. For example, syringe filters containing 0.45 μm are typically used for HPLC sample preparation and 0.2 μm is used for UHPLC. In life science applications 0.1 and 0.2 µm pore sizes provide sterilization of buffers, culture media, and additives.

a 0.45 mm syringe filter. No additional clean up of the sample solution was performed. Each milliliter of supernatant corresponds to 0.1 g semi-solid food matrix as the unit of conversion. A calibrant stock solution was prepared at a final concentration of 1 mg/mL of each analyte in ACN.
