New analytical tools for analysis of pesticide residues in food control

Prof. Amadeo Rodríguez Fernández-Alba will discuss the practical implementation of recent instrument advancements to address the golden triangle of pesticide residue analysis: (i) Sensitivity, (ii) Scope and (iii) Speed. For example, the improvement in sensitivity provided by high-end triple quads to mitigate matrix effects and new high-resolution MS systems which enable simultaneous and sensitive acquisition in both targeted and non-targeted analysis in a very consistent way. The sensitivity achieved is still less than that of triple quad MS, but they still achieve default values of 10 ppb. Dual-column chromatography with two columns connected to one MS not only improves utilization of the MS time but can also reduce the chromatographic analysis time to increase sample throughput without compromising selectivity. Alternatively, it can facilitate optimization of eluent compositions for both positive and negative detection modes, simultaneously, to improve LOQs for an increased number of pesticides without increasing the analysis time.

Richard will close with a brief update on developments in the analysis of polar cationic pesticides, options to either reduce or to eliminate the usage of helium as a GC carrier gas, and a new single software with some unique features for efficient data processing of pesticides data acquired by LC-MS, GC-MS and IC-MS.

Speakers: Prof. Amadeo Rodríguez Fernández-Alba, Reference Laboratory for pesticide residues in Fruits and Vegetables, University of Almería, Spain; Richard Fussell, Thermo Fisher Scientific

Powering productivity:  Advancements in technology and software for food safety & environmental analysis

Part 1: A user perspective on productivity gains using the Thermo Scientific 9610 GC-MSMS for pesticide residues analysis
Consumer interest in botanicals has grown considerably over the past few years as they are considered to contribute to overall health and wellbeing. Supplements are the most popular botanical products; therefore, manufacturers must ensure that the raw materials meet the criteria for identity, potency, purity, and limits of contaminants including pesticides. GC-MS/MS is most frequently used for the analysis of pesticides in botanical ingredients and helium is the most common carrier gas used for gas chromatography thanks to its high chromatographic efficiency and inertness. As helium availability and cost becomes increasingly challenging, options allowing a reduced helium consumption are being explored. NOW labs have evaluated the performance of the Thermo Scientific TSQ 9610 with the Thermo Scientific TRACE 1610 GC and the Thermo Scientific HeSaver-H2Safer for the analysis of ~250 pesticides in botanicals. Besides the benefits of the Nevervent feature, which allowed for undisturbed productivity, HeSaver-H2Safer carrier gas saving technology offered an innovative and smart approach to dramatically reduce GC carrier gas consumption.
Speaker: Mark Krzeszowiec, Method Development Supervisor, NOW Foods
Part 2: GC Hydrogen follow-up to NOW presentation
A short overview of the benefits and disadvantages of the use of hydrogen as a GC carrier gas for pesticide residues analysis.
Speaker: Ed George, Thermo Fisher Scientific
Part 3: Explore the possibilities with Thermo Fisher Scientific's PFAS testing solutions
Our comprehensive portfolio enables you to assess PFAS contamination across diverse matrices with high precision and productivity.
Speaker: Ed George, Thermo Fisher Scientific
Part 4: Utilizing a modern Chromatography Data System to power productivity in quantitative pesticide residues analysis
Pesticide analysis can be time-consuming and labor intensive, often leading to lengthy and error-prone data review processes. See how you can lower training and processing efforts and drive productivity with Thermo Scientific Chromeleon CDS software.
Speaker: Ed George, Thermo Fisher Scientific
Part 5: Extract more efficiently with walkaway automation from sample to vial
When preparing samples from solid matrixes, why settle for inefficient and error-prone manual processes when a better solution is at hand? Come along to find out about this innovative and productive solution and application examples.
Speaker: Michael Ebitson, Thermo Fisher Scientific
