  • How to Get Insight into Wines and Spirits: Fast and Reliable Chemical Analysis
  • Simple Mercury Analysis of Complex Samples: Soil, Oil, Foodstuffs, and More
  • Fast, Accurate, and Reliable Chemical Analysis of Water

From a chemical point of view, wine and spirits are very complex mixtures. According to the official prescriptions, many of their components should be precisely controlled to provide the required level of safety for consumers. Besides chemical control of all parts of the production chain – from vine to wine and from soil to oak barrel – is of utmost importance in order for manufacturers to make the right decisions and to answer questions like: when to start harvest, which must batch should be used immediately and which should be reserved, when to start malolactic fermentation, how the maturation process occurs and which oak types should be used. Finally, the quality of the resulting product must be confirmed not only by a renowned taster, but also by a precise chemical analysis.

Lumex Instruments has developed several analytical protocols to provide typical analyses of wine, wine materials and spirits at all stages of manufacture. These protocols can be realized on Lumex Capel capillary electrophoresis systems. We propose to determine the following important compounds:

  • Organic acids
  • Inorganic anions and some organic acids
  • Inorganic cations, biogenic amines and some amino acids
  • Aromatic aldehydes in brandy and cognacs
  • Sugars

These protocols are proposed in the form of Standard Operation Protocols, which means that every step is clearly stated in the text in detail and the entire procedure can be internally or externally validated, as has been done in many European countries.

In the webinar we are planning to talk in depth about the actual analytical tasks in the beverage industry and discuss in detail the proposed analytical methods.

Determination of mercury in complex samples presents specific challenges for laboratory analysis. This especially applies to soil, crude oil, wastewater, ores, foodstuffs, and biological samples. As a rule, these samples represent complex mixtures of various organic and inorganic compounds. Conventional AA and AF analysis techniques require lengthy stages of sample preparation and mercury accumulation on a sorbent. This significantly increases analysis time, labor cost, and error probability.

In this webinar, Lumex Instruments’ experts George Debus and Nikolay Ivanov discuss the advantages of atomic absorption spectroscopy with Zeeman background correction (ZAAS) for the analysis of mercury in a variety of samples. The ZAAS technique allows fast and selective direct mercury determination in any complex liquid or solid by means of pyrolysis/burning with real time detection. This method requires no sample preparation or mercury accumulation while an advanced thermal scanning option can provide additional information about forms of mercury and matrix.

LEARNING OBJECTIVES:

  • Examples of determination of mercury in soil, crude oil, naphtha, wastewater, foodstuffs, coal, sorbent traps, cosmetics, and more
  • Improved selectivity and sensitivity analysis using ZAAS
  • Compliance with ASTM, ISO, and US EPA standards
  • Determination of mercury species in samples

Mercury Analyzer

Inorganic anions and cations are major components of drinking water, and are responsible for its unique taste and hardness. However, some components, such as nitrite, bromide, strontium, manganese, and others represent risks to human health when consumed in excess of prescribed amounts. Other components, such as sodium and potassium should be consumed with caution among those at risk for heart disease or allergic reaction. Even fluoride, necessary for healthy teeth, becomes dangerous if taken in excess.

Knowing the ionic composition of other types of water, such as surface water, can aid in understanding both environmental processes as well as the influence of industrial activities on natural water sources. Information about ionic composition of processed waters (including waste water) can also provide insights into the effectiveness of treatment processes.

The analytical center of Lumex Instruments has developed several analytical protocols to analyze surface, natural, potable, and waste water samples using Capel capillary electrophoresis systems, also manufactured by Lumex Instruments. Join our expert as we offer an in-depth discussion of actual analytical tasks in the water industry and provide details of the proposed analytical methods.

IN THIS WEBINAR YOU WILL LEARN:

  • What analytical tasks are performed in the modern water treatment industry
  • Why it is so important to perform chemical analysis of all kinds of water samples
  • Compliance with ASTM, ISO, and US EPA standards
  • Which components can be precisely controlled with Lumex-developed protocols and how these protocols can be performed on our capillary electrophoresis systems
