(99.75/0.25; v/v). Before HPLC analysis, the extract was filtered through a syringe filter (0.20 µm PTFE filter). HPLC analysis of α-acids and iso-α-acids HPLC separations were performed on a Merck Hitachi Liquid Chromatograph (Merck, Darmstadt, Germany), consisting of a programmable HPLC pump (L-7100) with
PTFE Syringe Filters are universal filters that are inert to a wide variety of aggressive solvents and strong acids and bases. These syringe filters can also be exposed to high temperatures and are an excellent choice for HPLC sample preparation. We offer PTFE syringe filters in both their hydrophobic and hydrophilic states. PVDF Syringe Filters

Millex® syringe filters are available in sterile and nonsterile formats, offered in many membrane and housing options to enable compatibility with multiple solvents and sample types for applications including HPLC, UHPLC, and dissolution testing.
Aug 03, 2018 · In this paper, we report a simple method for the determination of quercetin, a typical antioxidant compound ubiquitously present in vegetable food products including grapes and wine. To this aim, 12 Italian wines were analyzed and the amount of quercetin was determined by high-performance liquid chromatography with ultraviolet detector. To reduce the interferences, a minimal sample preparation
Phenex syringe filters are designed for efficient and rapid filtration of almost any solution prior to analysis, and are optimized for superior flow rates and high throughput. Proper membrane and size selection are the keys to choosing the best product to maintain the integrity of your sample components as well as to protect your system from
Waters offers Pall Life Sciences laboratory filters for sample and solvent filtration, including: HPLC sample filters in syringe filter format. Solvent filters in membrane disc format. Solvent filtration apparatus. A wide selection of membrane types and pore sizes to deliver the right lab filter for any sample type, and a broad range of device
Jan 06, 2022 · Syringe nylon filters (0.45 µm) (Aijiren Technologies) were used. Methods Following HPLC systems were used: Aijiren HPLC (Santa Clara, CA, USA) and Shimadzu LC-40AD (Kioto, Japan).
Offering low extractable membranes and housing, Thermo Scientific™ Titan3™ Nylon Syringe Filters are HPLC performance tested, and color-coded to easily select the correct membrane and pore size. An enhanced Luer Lock inlet prevents leakage. A 1mm boro-silicate glass pre-filter is provided with most 30mm devices, pressure rated to 120psi.
Both Titan3 and Target2 syringe filters provide high-quality filtration solutions • Sample preparation for HPLC and UHPLC analysis • Protect columns and extend column lifetimes • Low sample volume compatibility • High integrity sample preparation Operating guidance Take sample from vial Twist syringe clockwise Push sample through
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.
