The Chemistry of Spices

Spices are a commodity found in every home around the world and often are used multiple times each day. The variety of spices is often only limited by the imagination. Each separate fragrance, color and taste is the result of a myriad of chemical interactions and reactions that gives each spice its own special character and place in our lives.Adulteration, counterfeiting and contamination of spices have dominated the headlines. The increased concern these past few decades has led to more research and increased scrutiny.SPEX CertiPrep examined spices from a variety of spice groups using ICP-OES and ICP-MS to get the accurate result of adulteration, counterfeiting and contamination of spices.

Is That Really bis (2-chloroisopropyl) ether: Potential Issues for EPA Methods 625 and 8270

The compound bis (2-chloroisopropyl) ether is a target compound in EPA methods 625 and 8270. This webinar is designed to educate the environmental community on some problems identified with bis (2-chloroisopropyl) ether that have existed for the past few years and seem to be worsening. There is widespread confusion about what compound B2CIPE actually is, and availability and costs are a known concern. We will discuss the identity of the material used as a reference standard, illustrate the issues and propose a solution to the problem. Other topics of discussion during the webinar include: What target compound is meant by bis (2-chloroisopropyl) ether? Issues we have observed in detection of the target compound. Additional isomers. Potential solutions to the issues.

Analysis of Beer, Wine and Components for Pesticides Using High Throughput Techniques & QuEChERS

There are hundreds of commercial pesticides in use in industrial and private agriculture. The concern over human pesticide exposure over the past few decades has led to the monitoring of these pesticides. Topics of discussion during the webinar include: Sample preparation Improving efficiency and accuracy with high throughput techniques Use of QuEChERS with a variety of types of agricultural products

Restricted Elements in Imported Children's Toys

The recording of our webinar entitled, "Identification, Preparation and Analysis of Imported Plastic Children's Toys for Restricted Elements." Topics of discussion include: Plastics IdentificationSample Toy PreparationSample Digestion Analytical techniques for determining elemental contentCorrelations between restricted organic content and inorganic elemental limits

Identifying and Quantifying the Uncertainty Associated with Classical Method (Titration)

In the field of analytical chemistry, great stress is placed on the precision of results obtained using a specific method. However, there is always uncertainty associated with the reliability of the results. Uncertainty calculations must be taken into account for each step of the analytical process, and estimating these values increases confidence in the accuracy of a measurement result.
