1-4mL Autosampler Vials for HPLC, UPLC, GC 16mm, 25mm Test Tubes for Water Analysis 6-20mL GC Headspace Vials

Aijiren polypropylene certified vials for autosampler use are translucent and chemically resistant. They are the vials of choice for pH-sensitive samples, sodium, or heavy metal analyses. Polypropylene vials come as either a snap vial style, crimp vial style, or screw vial style and can contain sample volumes up to 700 μL while leaving minimum

Apr 15, 2020 · Background A Simple, sensitive, and specific stability indicating reverse phase HPLC method was developed for simultaneous estimation of Lamivudine and Dolutegravir in bulk and tablet dosage form. Effective separation was achieved by injecting10 μL of the standard solution into Xbridge Phenyl (250 × 4.6 mm, 5 μ,100 A0) column, using a mobile phase composition of methanol: buffer (0.1% v/v

Jul 19, 2021 · Background A new, sensitive, suitable, clear, accurate, and robust reversed-phase high-performance liquid chromatography (RP-HPLC) method for the determination of brexpiprazole in bulk drug and tablet formulation was developed and validated in this research. Surface methodology was used to optimize the data, with a three-level Box-Behnken design. Methanol concentration in the mobile phase

Jan 31, 2023 · Purpose An analytical method using liquid chromatography with tandem mass spectrometry (LC–MS/MS) was established and validated for screening 425 drugs and poisons in dried blood spots (DBSs). Methods Blood (20 μL) was spotted on Whatman FTA™ classic card to prepare DBS sample, then extracted with 150 μL methanol and analyzed by LC–MS/MS using a multiple reaction monitoring method

Our portfolio includes clear glass vials for your general use and amber vial for applications involving light sensitive sample analytes. Our complete range of glass chromatography vials are made from Type 1 borosilicate glass which is compatibility with the widest range of sample matrices including acidic, neutral or alkaline pHs. The high-quality materials in use can minimize extractables leeching from the glass and interfering with the analytes of interest.

Innovative and carefully designed Thermo Scientific autosamplers and sampler extension module ensure reliable, precise and accurate injection for nanoliter to milliliter sample volumes. They support a wide range of formats and sample throughputs. Choose from rapid separation, nano, capillary, micro, standard, semi-preparative and more.

Vials Use only Aijiren vials, the shape, and the material is optimized for maximizing instrument precision. Do not overfill the vials. Fill the vial up to 1/2 to 2/3 of the total volume. Experimental conditions Make sure that the same solvents were used between the runs. Keep the room temperature constant and under 25 degrees Celsius.

Feb 9, 2014 · The aim of this study was the development of a new simple LC-MS method for the sensitive quantification of G and MG in snow and ice. Stir bar sorptive extraction (SBSE) with in situ derivatization is applied for extraction and enrichment of the analytes. SBSE is an equilibrium technique which uses stir bars with polydimethylsiloxane (PDMS) coating.

Feb 8, 2023 · To overcome the regular maintenance that is required for the nitrogen–phosphorus detector (NPD), which made it difficult to apply the method to clinical pharmacokinetic studies with high-sample throughput requirements, a sufficient sensitive, selective, accurate, and reproducible gas chromatographic assay using flame-ionization detection (FID

Jun 7, 2017 · 2.3.3 Ultra-HPLC. Ultra - HPLC (UHPLC) and ultra - performance liquid chromatography (UPLC) are based on the same technique. The term “UPLC” was trademarked by the Waters Corporation in 2004, based on using ≤2-μm diameter porous particles and operating pressures much higher than that of regular HPLC.

Uvison.com HTA HT1500U IC Autosampler - HT1500U: effective IC autosampler EFFECTIVE AUTOSAMPLER FOR ION CHROMATOGRAPHY AND FLOW-THROUGH-CELL APPLICATIONS • Easy-To-Operate • Support metal free applications • Removable racks for continuous feeding Compatible with any IC system, HT1500U has been engineered to offer the best balance between quality and affordability to perfectly fit the

When this mechanism is translated to the phenomenon of sample adsorption to containers, the stationary phase becomes the container material, the mobile phase becomes the sample solution being prepared, and the retention behavior of materials adsorbed onto containers is the adsorption strength. Fig. 1 Mechanism of Adsorption to Vials and Methods for Inhibiting Adsorption.

Jan 31, 2022 · For example, certified vials may be essential for sensitive trace analysis so that you can be sure that the peaks detected are definitely from your sample and not from the vial. For more routine analysis, certified vials will probably be an unnecessary expense.
