Application Notes
 
 
UHP-SEC Analysis of Biosimilars
 
The amounts of high and low molecular weight impurities are critical quality attributes for a therapeutic protein. Size exclusion chromatography (SEC), the standard technology for analyzing aggregation and fragmentation, was applied to elucidate the molecular similarity between an adalimumab biosimilar and the corresponding innovator product.
 
 
 
Highly Sensitive Determination of Contaminants in Surface Water in the Context of the EU Water Framework Directive using Stir Bar Sorptive Extraction (SBSE) and GC-MS/MS
 
In the work presented here, highly sensitive determination of around 100 contaminants in surface water in the concentration range from low doubledigit to low triple-digit pg/L was performed.
 
 
 
The Do’s and Don’ts of Working with Purified Water
 
Water is probably the most commonly used reagent in every laboratory. From reagent and buffer preparation to sample and standards dilution, water is everywhere. The potential impact of water quality on experimental results cannot be overlooked. It is important to learn a few ‘Do’s and Don’ts’ when handling purified water.
 
 
 
Quantitative determination of volatile organic pollutants in water using headspace–trap GC–MS
 
Headspace samples acquired on the Centri automated sample preparation and concentration platform were used to quantify a wide range of volatile organic pollutants in water. This work shows that in headspace–trap mode, Centri meets all the requirements and performs to the highest standard for this type of environmental analysis (EPA Method 524.2).
