Food Safety E-seminars
How efficient is your workflow when it comes to food samples? Are you sure you're seeing everything your sample has to offer? Learn how LECO has been expanding what is possible when it comes to food safety analyses with this free series of webinars.
Automated Thermogravimetric Determination of Moisture and Ash in Flour
The AOAC Official Method (925.10) Solids (Total) and Moisture in Flour utilizes a manual, air oven, loss-on-drying technique that is widely used in the food industry. AOAC Official Method (923.03) Ash in Flour also utilizes a manual, air oven, loss-on-drying technique. Learn from Jeffery Gast how an automated thermogravimetric moisture determination instrument like the TGA801 can follow both of the AOAC Official Methods' requirements for oven temperature and airflow while also reducing operator and analysis times, improving workflow efficiency.
Instrument: TGA801

Automated Thermogravimetric Moisture Determination of Meat and Semi-Solid Food Products
One of the most common moisture determination methods is a manual mass loss on drying using an air oven following the AOAC Moisture in Meat Method (950.46). Lloyd Allen will talk about how an automated thermogravimetric moisture instrument, such as the TGM800, meets the AOAC Official Method's requirements for sample mass, oven temperature, and air flow requirements while also reducing operator and analysis times, improving precision and workflow efficiency.
Instrument: TGM800

Optimization of Combustion Methods for the Determination of Low-Level Nitrogen/Protein in Food
Combustion techniques for determining nitrogen/protein in foods is gaining popularity due to shorter analysis times, ease of operation, and improved safety characteristics, but it is limited by the amount of sample an instrument is capable of analyzing at one time. Low-level nitrogen samples present a challenge to analyze due to sample characteristics and method limitations. Lloyd Allen, from LECO, will be discussing how to optimize methods for low-level nitrogen determination with combustion instruments.
Instruments: FP928, FP828P

Food Safety: A Journey Beyond the MOSH&MOAH Hump in Food Determination
The current analytical method for the quantitative determination of Mineral Oil Saturated Hydrocarbons (MOSH) and Mineral Oil Aromatic Hydrocarbons (MOAH) is LC-GC-FID, but the chromaticagraphic profile obtained is too often just a hump of unresolved substances. However, GCxGC-TOFMS/FID is the most promising solution to characterize MOSH and MOAH in detail and to detect markers that can help identify and act on the source of contamination. Giorgia Purcaro will introduce the challenges of MOSH/MOAH analysis and talk about what adding a GCxGC-TOFMS analysis to your process can do for your results.
Instruments: Pegasus® BT 4D, GCxGC ECD/FID

Application of Two-Dimensional Gas Chromatography with Mass Spectrometric Detection for Analysis of Pesticide Residues in Foodstuffs
The Czech Agriculture and Food Inspection Authority has been using GCxGC-TOFMS for the analysis of pesticide residues in food of plant origin since 2005. Radim Stepan will talk about the advances in the instruments and the analyses they have used for pesticide residue analysis in cooperation with the University of Chemistry and Technology Prague.
