Pesticides are widely used in agriculture to protect crops and maintain yield, but their presence in food must be carefully monitored. To safeguard consumers, regulatory authorities worldwide set maximum residue limits (MRLs), often at very low concentrations and across a wide range of compound classes.
For food testing laboratories, pesticide residue analysis is therefore one of the most demanding routine workflows. Labs are expected to deliver reliable, reproducible results across diverse food matrices, while maintaining throughput and keeping pace with evolving regulatory expectations.
Why pesticide analysis remains challenging
Modern pesticide testing rarely focuses on a single compound. Instead, laboratories must routinely screen and quantify large, multi‑residue panels that include compounds with very different chemical properties.
Common analytical challenges include:
Successfully addressing these challenges requires analytical workflows that combine sensitivity, selectivity and robustness, while remaining practical for routine compliance testing.

Supporting reliable multi‑residue workflows
LC‑MS/MS has become the technique of choice for pesticide residue analysis in food due to its ability to deliver high sensitivity and selectivity across broad analyte panels. For routine testing environments, systems that support fast polarity switching, stable performance, and consistent data quality allow laboratories to consolidate more compounds into fewer runs.
Equally important is data handling. Integrated software platforms that bring acquisition, processing and reporting together can help laboratories manage high sample volumes while maintaining confidence in results and simplifying day‑to‑day operation.
Polar pesticides: A distinct analytical challenge
Within the broader pesticide landscape, polar pesticides, such as glyphosate, glufosinate and aminomethylphosphonic acid (AMPA), present additional difficulties. Their poor retention on conventional reversed‑phase LC columns and susceptibility to matrix interferences make them particularly challenging to analyze.
A recent technical note demonstrates how a dedicated workflow for polar pesticides can address these challenges: Quantitation of polar pesticides in foods of plant origin
The study describes a combined sample preparation and LC‑MS/MS approach for the analysis of polar pesticides in tomatoes, oranges and oats. Key elements of the workflow include:
The results show reproducible chromatography, reliable quantitation and performance at low µg/kg levels across multiple plant‑based matrices, supporting confident compliance testing for this difficult compound class.
Enabling confidence in routine compliance testing
As regulatory expectations continue to evolve and analyte lists grow, food testing laboratories need approaches that are both technically robust and operationally sustainable. Well‑designed LC‑MS/MS workflows, supported by clear, application‑focused guidance can help labs maintain confidence in their results while meeting productivity demands.
By combining sensitive instrumentation, streamlined data handling and practical technical references, laboratories are better equipped to adapt to changing requirements and deliver reliable pesticide residue data in support of food safety.

Glycosylation is one of the more structurally diverse and biologically impactful PTMs in protein therapeutics. Both N‑linked and O‑linked glycans influence protein folding, stability, and biological activity. Given these effects on biotherapeutics, glycosylation is a closely monitored critical quality attribute (CQA). Comprehensive and site‑specific characterization of glycosylation is essential for informed decision‑making throughout drug discovery and development.
Warranty expiration is more than an administrative milestone—it is a transition point that can significantly impact instrument uptime, laboratory productivity, operating budgets, and scientific outcomes.
For more than 20 years, the CDCO has supported academic, commercial, and not‑for‑profit drug discovery programs with deep expertise in pharmaceutical lead optimization. Within the bioanalytical group, their role is to enable rapid and reliable decision‑making through quantitative analysis of candidate drugs in biological matrices.
