Fully Automated Determination of The Permanganate Index in Accordance with DIN EN ISO 8467

Metrohm presents a method for completely automated determination of the permanganate index according to DIN EN ISO 8467 (DIN 38409-5). The determination of the permanganate index is a standard application performed in almost all water laboratories but keeping the quality of sample preparation consistent — including the time-critical heating of samples — is a challenge.

Method Development and Optimization for LC/MS/MS

19 May 2014 - 20 May 2014 09:00 - 17:00

Venue: Symbion Science Park, Copenhagen, Denmark  
Price: US$ 1380

This two-day class is ideally suited to analytical chemists and laboratory managers in GLP/GMP regulated industries such as pharmaceuticals, diagnostics, biotechnology, cosmetics, and food. Every chemist developing LC/MS/MS methods in any industry, agency or school must take a systematic approach to ensure valid methods and the quality of their results.  Therefore, this course is for everyone who is presently using LC/MS, may use LC/MS in the future, or who must understand and evaluate data from LC/MS analyses.

 

Mass Spectral Interpretation

21 May 2014 - 22 May 2014 09:00 - 17:00

Symbion Science Park, Copenhagen, Denmark
Price: US$1,380

The two-day training course on interpretation of mass spectra is designed to develop the fundamental skills necessary to understand fragmentation of ions formed by electron ionization (EI) in GC/MS or by one of the soft ionization techniques employed in LC/MS. Many of the examples are taken from EI mass spectrometry; however, the principles that are learned are applicable to any ionization technique.

Classification of Chamomile Flowers, Essential Oils and Commercial Products Utilizing Chemometrics and the Agilent GC/MSD

Presenter: Professor Jon Parcher (National Center for Natural Products Research, School of Pharmacy, University of Mississippi)

ON-DEMAND

In collaboration with Agilent Technologies

This is a presentation of the application of gas chromatography with mass spectrometric detection (GC/MS) for the analysis and characterization of essential oils with a particular emphasis on chamomile. Analysis of essential oils can be performed by a variety of techniques; however, in this presentation the advantages of GC/MS will be discussed.

 

A New Dimension in Benchtop GC-MS

Presenters: David Sparkman (University of the Pacific, USA) & Nick Bukowski (Markes International, UK)

In collaboration with: Markes International

ON-DEMAND

This webinar will introduce Select-eV, a revolutionary development in electron ionisation. Until now, soft ionisation by EI hasn't been successfully achieved without a significant sensitivity penalty. Select-eV provides the ability to switch effortlessly between hard and soft ionisation without any loss in sensitivity. This presentation will demonstrate how the underlying benefits of GC-TOFMS along with the ground-breaking capabilities of Select-eV technology have been combined into a compact analytical system, BenchTOF-Select.

 

 

 
 
 

HPLC Solutions #121: Autosampler Design, Part 2: Needle-in-Loop

In the last instalment of HPLC Solutions (#120) we looked at one popular autosampler design, the push-to-fill autosampler. Now we’ll turn our attention to the other most popular design, which I call needle-in-loop.

 

 
 
 

MS Solutions #28: Quality: The Third Side of the Analytical Success Triangle

As analytical chemists, we spend considerable time thinking about and working with basic scientific principles combined with the technology and products that allow us to solve our analytical problems. However, it is essential for success of any method and for the long-term success of a laboratory operation that our science and technology are supported by a quality system that ensures continuing achievement of our operational goals. We therefore present a triangle concept for analytical success: One side of the triangle shows our need to understand fundamental scientific concepts. A second, and equally sized side, is the ability to apply current technology, applications, software, and techniques in the laboratory. Finally, the base of this equilateral triangle is the quality system. If any one side of the triangle is given inadequate attention or, worse yet, is missing then we cannot hope to achieve overall success for the laboratory operation.
