Mycotoxins, Fluoroquinolines, Colors:
Boosting Sample Preparation

Food safety is an increasingly important topic for our global food supply. Quality data are critical to ensuring safe food. Although many advances in the sensitivity and applications of analytical techniques have occurred, often sample preparation has lagged behind. Solid-phase extraction (SPE) has shown utility in both clean-up and concentration of food extracts. How do you move into automation of cartridge SPE? Improved accuracy and precision with less hands-on time for a variety of food safety analyses will show the utility of this approach.

  • Understand the role that solid-phase extraction plays in sample preparation
  • See how automation can help improve results compared to manual operation
  • Understand real examples of food safety analyses, such as aflatoxin, deoxynivalenol, and fluoroquinolone

Adding Confidence to Your Results:
The Advantages of a Comprehensive HRAM Library
and Compound Database in Food Analysis

MAY 6, 2015, 2 PM EASTERN

The use of high-resolution accurate mass (HRAM) LC/MS instrumentation for the analysis of pesticides in food samples is growing in routine analytical laboratories.  It allows both screening and quantitation for large numbers of analytes in a single injection at concentrations at or below maximum residue limits (MRLs), and can offer better specificity and ease-of-use when compared to setting up complex methods on standard triple quadrupole instrument platforms.
In this webinar, we will discuss the use of a new HRAM library with a corresponding compound database for added confirmation of results in the analysis of over 500 pesticides by full scan data-dependent MS2 in QuEChERS extracts on the Thermo Scientific™ Q Exactive™ Focus hybrid quadrupole-Orbitrap™ mass spectrometer.

Key Learning Objectives:

  • Learn about the acquisition modes of Q Exactive Focus MS
  • Learn how to perform combined quantitative and qualitative analysis in one measurement
  • Learn how to make residue analysis more efficient and effective

E. coli Testing - Let Automation Take the Strain


Safeguarding the food supply from the presence of harmful pathogens is an ongoing concern for food producers. Recent FSIS regulations require testing for the E. coli virulence factors stx1/stx2, eae, and O157. If these virulence factors are found to be present, further testing is required to determine the presence of adulterant O serotypes such as O157:H7 and the Big-6 non-O157 serotypes.

This webinar will discuss:

  • A novel screening system for E. coli virulence factors
  • The harmonized application of an innovative one-for-all workflow sample preparations and detection solution for DNA-based screening of E. coli virulence factors, as well as for established parameters of Salmonella and Listeria spp.
  • How the presence of E. coli O157:H7 or non-O157 serotypes can be determined using the same equipment and workflow

Meeting GFSI Standards: Reducing Contamination Risks
of Compressed Air in Food Plants

Understanding the requirements for compressed air in a food plant can be confusing.  You have a GFSI auditor coming: What will they be looking for?  What does good look like?  What type of filtration should I have in place at point of food contact?  What standards apply to compressed air contacting food?  How do I test my air?

Please join us for a webinar so you can better understand:

  • What are the contamination risks from compressed air
  • How to meet GFSI requirements for compressed air filtration
  • GMPs and SSOPs for compressed air in your food plant
  • The basics of compressed air testing

Laboratory Proficiency Testing: Past, Present and Future

Proficiency testing is an essential part of laboratory quality procedures, particularly ISO 17025, which is the standard for which most labs must hold accreditation in order to be deemed technically competent in most major countries. In many cases, suppliers and regulatory authorities will not accepts test or calibration results from a lab that is not accredited. Taking part in proficiency tests provides confidence in your company’s laboratory equipment, methods and staff, and assurance that you are delivering the quality results demanded by your customers.

In this webinar, you will learn:

  • The role of proficiency resting in the food sector
  • Why proficiency testing is important for your business
  • The future of proficiency testing for your company as the food testing market evolves

Improved Identification of Pesticides Using Atmospheric Pressure Gas Chromatography-Mass Spectrometry

Mass spectrometry offers residue chemists the ability to discriminate against thousands of peaks, identifying trace-level residues in a variety of food matrices, but can result in false positives or -negatives. The use of atmospheric pressure ionization gas chromatography (APGC) allows for better identification of residues using atmospheric pressure ionization. This technique, coupled with high-resolution quadrupole time of flight mass spectrometry, provides the ability to confidently identify analytes in challenging food matrices.

This presentation will provide:

  • An explanation of how APGC works under dry and wet source conditions
  • A comparison of mass spectrometry approaches
  • Examples of how APGC produces selective peaks for certain pesticides prone to excessive fragmentation in the presence of complex food matrices

Accessible Mass Detection for Food Testing: From Nutritional Composition to Contaminants Testing

Mass detection is complementary to traditional detectors used for liquid chromatography and, in some cases, has begun to replace previous detection methods. It offers the opportunity to decrease detection limits, as well as obtain mass spectral information on the components in the sample. The combination of both chromatographic retention time and mass information results in increased selectivity for the analysis of compounds in food. In this webinar, we will present mass detection methods, including the analysis of vitamins, non-nutritive sweeteners, food colors, and mycotoxins.

Learn How The Addition of Mass Detection Can:

  • Simplify matrix complexity
  • Extend detection capabilities
  • Enhance confidence in compound identification

Validation and Verification of Microbiological Methods in the Food Laboratory: Tales from the Trenches

Food labs are often faced with a unique set of challenges when choosing and validating methods for use in their laboratory. With multiple clients, regulatory agencies and sample types to account for, this can be a daunting process. In order to accommodate all of these factors, the use of multiple rapid methods is often required to meet the needs of each client and sample type. Once the decision has been made to utilize multiple methods, the next critical step is validation. Many laboratories have accepted performance claims from internationally accepted certifying bodies such as AOAC, AFNOR or MicroVal or current literature. It should, however, never be assumed that a method will perform as claimed in every laboratory and for every sample matrix for which it will be used. Additionally, it is vitally important to establish that the methods that are used in the laboratory are performed properly and with a high degree of confidence.

This webinar will focus on the following:

  • Factors Influencing Fit-for-Purpose of a methods
  • Considerations for meeting client needs
  • Impact of validated methods on ISO/IEC 17025 requirements
  • Real life examples of how method validations can be conducted in the independent laboratory will be presented
