Aug 7, 2018 · Charting compatibility. Hopefully, this quick overview helps you identify the most appropriate membrane-solvent combination for your application. To compare between all the common membranes and solvents, review the chemical compatibility chart in our guide to laboratory membrane filtration principles and chemical compatibility.

Jan 28, 2021 · Mobile phase composition is a fundamental decision which has a major impact on the separation of analytes in your HPLC or UHPLC method. It has an effect on retention time of analytes, selectivity between these and the peak efficiency.

Jun 27, 2023 · In general, modern chromatography liquid autosamplers accept 12 x 32mm vials, so we will assume that a 12 x 32mm vial is compatible with your autosampler (Headspace autosamplers accept 20mm wide

Apr 9, 2021 · Unanticipated incompatibilities between the drug product and a closed system transfer device (CSTD) delay therapeutic delivery to the patient. Considering the CSTD with the drug product and even co-packaging the drug product with an optimal FDA-approved CSTD will positively impact drug product therapeutic performance and ultimately patient care.

Choosing the right septa for your work. In the same way that chemical composition underpins the choice of a vial, chemistry is an important factor in choosing the right septa for your work. The best analytical performance will be achieved with a septum in the cap of your vial that protects your sample and is as chemically inert as possible.

Jun 13, 2023 · Step 3: Determine Vial Material. Glass Autosampler Vials: The most common type of Autosampler vial is the Type 1 Borosilicate Glass, which represents the least reactive glass. Type 1 glass has the least pH shift (lowest leaching characteristics) and a Coefficient of Expansion = 33 for Clear and 51 for Amber. Plastic Autosampler Vials:

Sep 12, 2021 · Mobile Phase. The most common mobile phases for gas chromatography are He, Ar, and N 2, which have the advantage of being chemically inert toward both the sample and the stationary phase. The choice of carrier gas often is determined by the needs of instrument’s detector. For a packed column the mobile phase velocity usually is 25–150 mL/min.

The melting point of polypropylene is 160°C / 320°F) Low temperature threshold: polypropylene becomes brittle below 0°C. NOT compatible with strong oxidants. Polypropylene Chemical Compatibility Chart: Check the chemical compatibility of Polypropylene with various chemicals, solvents, alcohols and other products. Shop Polypropylene.

Apr 29, 2020 · Inorganic membranes are resistant to chemical degradation from a wide range of HPLC solvents. Be aware that Teflon filters cannot be used with water due to the material’s nonpolar characteristics. HPLC mobile phase filters have a pore size of around 4.5 microns. The requirement for filtration of HPLC mobile phases is always a hotly debated topic.

Use the simple online Thermo Scientific SureSTART Selection Guide to find the right septa and vial for your analysis. Thermo Scientific SureSTART Selection Guide Answer a few simple questions and our SureSTART Selection Guide will recommend the best septa, cap, and vial for your workflow.

Chemical Compatibility. Buffer composition, along with mobile phase pH, must be chosen in agreement with column housing material and nature of the stationary as well as different parts of LC instrument (pumps, tubing's, etc.) phase to prevent corrosion or degradation of either.

Guidelines and tips for choosing the right bottle for your lab application Nalgene containers are made from a wide variety of plastic types to meet the needs of virtually any laboratory application. Care should be taken to ensure chemical compatibility between the type of plastic chosen and the intended contents of the bottle.

Choosing the right vials and well plates Vial and well plate products are an essential part of every chromatographic workflow—from sample storage and containment to analysis—and the products you choose can have an impact on the performance, reproducibility and accuracy of your results, as well as your profit margins.

Jun 21, 2023 · Factors to Consider for your vial labels 1. Adhesive Compatibility. To guarantee a secure bond between the label and the vial, it is vital to consider adhesive compatibility. Different materials require specific adhesives to ensure optimal adherence. For instance, plastic vials may necessitate a different adhesive than glass vials.

Diferent septa material for LC and GC applications. There are many diferent types of materials used to produce the septa found in LC and GC vial caps. This document will provide you with the technical guidance you need in order to make the right selection.
