Odor Control Filter for Marine, Boat, RV

Boats, yachts, and RVs often face odor issues from holding tank vents and waste system discharges. Odor control is difficult because of the constant release of gases from waste decomposition, which can quickly accumulate in small, enclosed spaces. Factors like high humidity, heat, and limited ventilation in marine and RV systems can intensify odor problems and make them harder to manage. Industrial Odor Control provides rugged?vapor-phase activated carbon vent filters?that capture odors before they are released ...

Determination of organic acids in feedstuff, silage, haylage, and fermentates for biogas plants

To provide the proper conditions for silage or haylage storage in agriculture it is necessary to regularly monitor the formation of certain organic acids in it. For example, the formation of butyric acid can indicate spoiling of material. Formic or propionic acids can be artificially added to increase the nutritional quality. The same materials and some other biodegradable waists (agricultural residues, sewage sludge, etc.) are also used in biogas plants, where the fermentation process must be carefully monitored, ...

Determination of organic acids and some preservatives in wine and spirits

The organic acids profile in wine is a highly informative parameter since it reveals important features of the whole technological process. It is also one of the most important criteria for wine authentication. In spirits like cognac, brandy or whiskey, the presence of certain organic acids can indicate the violation of distillation or maturation processes or reveal the tendency to precipitate during storage. Some organic acids (sorbic, benzoic, ascorbic) can serve as preservatives; their presence is strictly ...
