8 Minimising sample loss with low-reactivity uncoated autosampler vials
In high-precision analytical workfl ows, even the vial can infl uence your results. Microsolv’s RSA™ (Reduced Surface Activity) Autosampler Vials are uniquely engineered to eliminate a common source of variability - surface interactions - without relying on coatings. By starting with a cleaner, more inert glass surface, RSA™ vials help ensure your samples stay true from injection to analysis.
Unlike coated vials that rely on surface treatments to reduce reactivity, RSA™ vials are completely uncoated. Instead, they are manufactured using a proprietary process that inherently reduces surface activity in the glass itself. This eliminates the need for coatings, which can degrade over time or introduce unwanted variables into sensitive analyses.
By minimising reactive sites such as silanols, RSA™ vials provide a more stable and inert environment for your samples. This is especially critical when working with low- concentration or adsorption-prone compounds like peptides, proteins, and basic drugs.
Designed for universal compatibility with all major autosamplers, RSA™ vials are a practical upgrade for laboratories aiming to improve reproducibility and reduce variability. Whether you’re conducting pharmaceutical, environmental, or clinical research, these uncoated vials offer a dependable solution for high-performance workfl ows.

Custom degasser improves precision in polymer viscosity analysis
Biotech Fluidics AB has collaborated with Spanish polymer analysis specialist Polymer Char to integrate a customised DeGASi® degasser into Polymer Char’s Intrinsic Viscosity analysers - optimising reliability and data quality for polymer characterisation.
In viscometric analysis, particularly relative viscometry, the presence of dissolved gases such as oxygen and carbon dioxide in high-purity solvents can lead to microbubble formation during temperature shifts or fl ow changes. These bubbles can destabilise detector signals and introduce pressure variations, compromising the accuracy and reproducibility of viscosity measurements.
By incorporating an optimised degasser, these risks are signifi cantly reduced. The degasser continuously removes dissolved gases from the solvent stream, improving fl ow consistency and enhancing signal stability - both essential for robust analytical performance.
Alba Cárdenas, Intrinsic Viscosity product expert at Polymer Char, explained:“We turned to Biotech Fluidics for their deep expertise in degassing and their openness to customisation. The result is a degasser that fi ts seamlessly into our systems, delivering smoother fl ow and better signal-to- noise ratios, which are crucial for achieving high-quality, repeatable results.”

Expanded HPLC system enhances spectral insights for biopharma QC
Waters Corporation has added photodiode array (PDA) detection to its Alliance iS Bio HPLC product line, further supporting spectral analysis for biopharmaceutical development and quality control.
The enhanced system delivers up to 80× greater out-of-the-box sensitivity when paired with MaxPeak™ Premier columns, improves reproducibility more than threefold, and reduces carryover by up to two orders of magnitude. PDA detection enables multi-wavelength analysis, impurity profi ling, and peak purity assessment.
Designed to minimise user error and streamline workfl ows, the platform is available in four confi gurations for small- and large-molecule analysis. It is fully compatible with Waters’ Empower™ Chromatography Data System and laboratory information management systems (LIMS). The system has also been awarded ACT environmental certifi cation by My Green Lab.

How brewers and cider makers can stay on top of ABV limits
For today’s brewers and cider makers, getting alcohol by volume (ABV) right is more than a quality issue, it’s a legal requirement and a matter of consumer trust. Whether you’re producing a traditional ale, a crisp cider, or a non-alcoholic beer or cider, accurate testing is what ensures that what’s on the label is exactly what’s in the glass.
In the UK, a drink labelled ‘alcohol free’ must contain no more than 0.05% ABV. In the United States and much of Europe, the limit is 0.5%. For non-alcoholic beer and cider, even a fraction of a percent over can mean fi nes, product recalls, or losing vital retail contracts. With demand for alcohol-free products increasing year on year, the scrutiny on producers has never been higher.
That is why many breweries and cideries are choosing the Ellutia 200 Series Gas Chromatograph. Compact, user friendly, and designed for real world production environments, the 200 Series GC with Flame Ionisation Detection (FID) delivers ethanol measurements with precision down to 0.01% ABV. For producers, that means knowing with confi dence that their non-alcoholic beer and cider products meet regulatory standards, and keeping their promises to customers.
The benefi ts of bringing ABV testing in house go far beyond compliance. Producers can: confi rm fermentation is progressing as expected; verify alcohol free and non-alcoholic beer or cider claims before packaging; catch off target batches early, avoiding costly relabelling; maintain fl avour consistency and shelf stability across every release.
A leading global brewer recently adopted the 200 Series GC to protect its alcohol-free and non-alcoholic range. By running quick, routine checks on site, they confi rmed every batch remained below 0.05% ABV, even at scale. The result was faster decision making, fewer risks of regulatory setbacks, and stronger trust from retail partners and consumers alike.
With straightforward workfl ows and minimal sample preparation, the 200 Series GC integrates seamlessly into production routines. From mid fermentation checks to fi nal bottling validation, it gives brewers and cider makers the data they need to keep non-alcoholic beer and cider consistent, compliant, and ready for market.
As the low and no alcohol sector continues to grow, investing in accurate, in house ethanol testing is not just good practice, it’s essential. Read the case study:
