Waters Calibration Standards are expertly created to give you precise molecular weight reference materials that are easily packed to reduce errors in pertinent calibration techniques. A single calibration standard is frequently used to confirm a component's molecular weight in a sample mixture. The molecular weight identification process is made simple and uncomplicated by these individual component standards.
An individual GPC standard (Gel Permeation Chromatography standards) for molecular weight determination is the product specified here. The standard for polyethylene oxide is 40,000 Da. To review the entire Waters product line, or if you are interested in checking out additional Standards similar to the Polyethylene Oxide Standard 40,000, you can browse our brochure or visit our website, where you can easily shop for lab equipment based on your laboratory's needs.
Similar to the Polyethylene Oxide Standard 40,000, you may also want to check out the Neutrals QC Reference Material available on our website; It is possible to utilize the Neutrals QC Reference Material with any chromatographic systems that have a UV detector. It is meant to serve as a benchmarking standard for systems. There are solely neutral chemicals in the mixture. The QC Reference Material will give you confidence in your results, cut down on troubleshooting and rerun time, and allow you to compare results from different laboratories when used consistently and with control charts. This reference material can be used with many different separation techniques. One ampule with 10 μL/mL acetone, 0.25 mg/mL naphthalene, and 0.4 mg/mL acenaphthene in 50/50 acetonitrile/water, 2 mL, makes up the Neutrals QC Reference Material Kit.
What Is The Polyethylene Oxide Standard 40,000's Shelf Life?
The Polyethylene Oxide Standard 40,000 has a 36-month shelf life and can be safely stored in a refrigerator at 4 degrees Celsius; however, we highly recommend using the standard up within a week of reconstitution.
Can I Inject More Than One Standard At A Time If I Use Narrow Standards?
The ability to inject a variety of standards is typically available in GPC with RI detection, although this is only appropriate if the eluted standards have an adequate resolution. We advise against applying more than three criteria simultaneously. We advise employing and injecting only one standard at a time when using sophisticated detection, such as viscometry, when the area under the curve for a standard needs to be precisely defined.
