Waters: Processing and Interpreting LC/Time-of-Flight MS Data

December 12, 2018 @ 1:00 pm - 2:00 pm EST

Mass spectrometry (MS) is becoming more and more common in the day-to-day work of analytical scientists either as a supplement to, or enhancement of, UV and other optical-based measurements. The additional information provided by mass spectrometry is of value in a variety of assays across multiple application areas. For example, Time-of-Flight (TOF) mass spectrometry provides accurate mass measurement for compound confirmation or identification of unknown species. It can also provide enhanced specificity over traditional MSMS techniques in quantitative assays. In…

Amino Acid Analysis: Challenges and Solutions

February 28, 2019 @ 1:30 pm - 2:30 pm EST

Amino acids are small molecules that serve as fundamental building blocks in a cell. They play a vital role in a variety of physiological mechanisms. Quantitation of amino acids to understand and monitor cell function has historically been a challenge to researchers. This presentation will not only shed light on the challenges in amino acid analysis but also present ways of addressing those challenges.     Speakers Laks Iyer, Ph.D. Principal Product Manager Waters Corporation   Laks Iyer Ph.D. is…

Unexpected Purity Differences Between Popular Bottled Waters

May 22, 2019 @ 2:00 pm - 3:00 pm EDT

Join us for this complimentary webinar discussing different bottled water samples that were analyzed for cleanliness and purity. Teledyne Tekmar performed a study on 5 popular bottled waters using proven Total Organic Carbon (TOC) analysis. TOC is a great “catch all” method of validating water cleanliness and purity. We will be using Teledyne Tekmar’s Fusion because it offers the best choice for drinking water purity analysis. This is due to its oxidation technique which allows for very few interferences and…

Webinar: An Introduction to characterization of biomolecules using analytical ultracentrifugation

June 18, 2019 @ 8:00 am - 9:00 am EDT

ABSTRACT: DATE: June 18, 2019 TIME: 8:00am PDT Analytical Ultracentrifugation (AUC) is one of the most powerful biophysical tools used today for the characterization of biological samples ranging from small drug molecules to intact viruses, vesicles and microparticles. AUC works with biological samples in the native state and does not depend on a reporter species or custom-coated substrates which are required by techniques such as NMR, EPR, SPR and fluorescence spectroscopy. AUC separates biomolecules based upon both molecular mass and…

Webinar: Tips and tricks for more accurate digital PCR

October 24, 2019 @ 6:00 am - 7:00 am EDT

In this expert webinar, Dr. Kubista will share with you the experience he and his team have gathered at the TATAA Biocenter, developing applications and providing services using digital PCR for nearly 12 years. They have experienced all the problems common to dPCR analytical workflows and developed robust standard operating procedures to minimize the risk of error and maximize robustness and repeatability, and developed various controls to test the performance and validate the methods. He will also discuss dPCR assay…

Webinar: QIAGEN’s new dPCR portfolio – overcoming the current throughput, speed and usability bottlenecks in digital PCR

November 14, 2019 @ 6:00 am - 7:00 am EST

Digital PCR (dPCR) is a highly viable solution for copy number variation (CNV) detection, rare mutation detection and quantification, validation of NGS results, and applications alike. It offers significant advantages over quantitative PCR (qPCR) with regards to precision, reproducibility, and sensitivity, coupled with the ability to obtain absolute quantitative results without the need for standard curves. That is why, over the last years, many researchers have come to use dPCR, resulting in over 4500 publications until the previous year. However,…

Webinar: Advantages of digital PCR and its applications – the power of partitioning

December 12, 2019 @ 6:00 am - 7:00 am EST

The versatility of standard PCR and qPCR is well known. Digital PCR is now taking this to a whole new level. The power of partitioning enables you to explore new frontiers which have been limited with present-day standard technologies: the more partitions, the higher the resolution and sensitivity. Besides, with more partitions, a higher volume of diluted sample can still be analyzed. QIAGEN’s digital PCR technology is superior to any standard technology in handling difficult samples with inhibitors or complex…

Redefining the Limits of Handheld Raman Spectroscopy

February 19, 2020 @ 11:00 am - 12:00 pm EST

OVERVIEW Recent advances in handheld Raman spectroscopy enable both higher sensitivity qualitative analysis and quantification of finished products. New methods remove the requirement for wet-chemical methods that require significant time and resources to use, such as liquid chromatography. Applications such as counterfeit identification and quantification are now possible with a handheld instrument which can be conveniently used outside the laboratory. With Raman spectroscopy it is possible to differentiate between authentic, counterfeit, and reverse-engineered pharmaceuticals and quantify solid dosage forms. In…
