Efficient Quality Analysis of Biodiesel using GC - NEW!

Biodiesel is a renewable fuel alternative to petroleum diesel. It can be used in a pure form or blended with petroleum diesel to form a product that can work in conventional diesel engines without modification. The quality of the final product must be monitored to ensure reliable engine operation. Bound and free glycerin content can indicate the quality of biodiesel. A high content of free and total glycerin can lead to buildup in fuel tanks, clogged fuel systems, injector fouling and valve deposits. The analysis of biodiesel following ASTM methodology for glycerin by gas chromatography (GC) will be presented.

Improved Precision in Headspace Blood Alcohol Analysis - NEW!

Precision and accuracy are of utmost importance in Blood Alcohol analysis because an analysis must be scientifically sound, but more importantly must withstand examination in a court of law.

This webinar will demonstrated the ability of HS-GC to meet and exceed state regulated precision and accuracy proficiencies, while maintaining a run time of less than 3 minutes. The data presented in this study will show that over the course of 3 months and more than 500 sample injections a standard with 0.19% ethanol achieved an RSD of 1.23%. This demonstrates a method that is not only is the method fast, but extremely precise, accurate, and most importantly robust.

Increased Productivity in Drugs of Abuse Analysis - NEW!

Techniques for detecting drugs of abuse in biological samples have greatly improved with advances in analytical instrumentation. Bench top GC/MS systems are the instruments of choice for forensic scientists. These instruments are legally defensible in court as they are able to positively identify the presence of drugs in urine and blood samples. Even though mass spectrometry technology is advancing, forensic scientists are still hindered by time consuming extractions that must be performed for specific drugs of abuse.

One fundamental problem encountered is the need for multiple extractions for both identification and quantitation of particular analytes. The PerkinElmer Gas Chromatograph/Mass Spectrometer (GC/MS) is capable of positive identification as well as quantification of a drug in the same injection though the use of SIFI (Single Ion Monitoring and Full Scan in the Same Run). The result is that only one extraction and one injection using the GC/MS system is necessary. In the past it took multiple extractions and multiple chromatography analyses.

This SIFI technique will be demonstrated along with other optimized techniques using the industry standard GC/MS technology for increasing the productivity in Drugs of Abuse.

Automating HPLC Method Development, Robustness Testing & Validation
Duration: 1 hour and 10 minutes
Basic principles and approaches regarding HPLC method development are presented including preliminary considerations, running initial scouting runs, procedures for setting up a series of experiments (a survey), and valuable pointers on evaluating the results. Throughout, the key optimization parameters are discussed and evaluated.

Based on the initial results, suggestions are provided for follow-up experiments, including interpolation routines. These are intended to help gain additional information and possible improvements to the method.

Finally, strategies for method robustness testing are discussed as a part of initial method validation.

HPLC Troubleshooting (Part 2 of 2*): Recognizing diagnostic clues and interpreting chromatographic results
Duration: 117 minutes
Basic troubleshooting strategies will be applied, covering all aspects of an HPLC system. This will include discussions on how to best use all your clues in order to isolate the problem(s). Clues from instrument components, chromatograms and results will be explored. Also, various symptoms are related to possible HPLC problems and the probable causes of these problems are explored. Example data/results are diagnosed to demonstrate and promote good troubleshooting skills.

* Attending Part 1 is helpful, but not necessary.
