The hidden costs you’re paying for in-house pesticide reference standards
Time wasted on in-house preparation
Your technicians are too valuable to waste hours making standards. Every minute spent weighing, diluting, and documenting is time not spent on revenue-generating testing. Our ready-to-use standards arrive with certificates of analysis, so they can get straight to their most valuable work.
Quality uncertainties that compromise results
When you make standards in-house, variables creep in. Different technicians, different days, different results. Our standards are manufactured under strict quality protocols with documented traceability, eliminating a major source of uncertainty in your testing process.
Resource drain on your lab
Scheduled deliveries aligned with your consumption ensure you always have fresh standards.
Audit and compliance headaches
When you’re audited, your in-house standards documentation better be flawless. Or you could simply rely on our comprehensive certificates of analysis, complete with traceability and expiration dates. Which sounds easier?

Who uses our pesticide reference standards?
Environmental testing labs
You're facing EPA scrutiny with methods like SW-846 8081B and 8270E while juggling state-specific requirements that vary wildly. Miss a QC requirement and you risk losing your NELAP or state certifications. When your customers are cleaning up Superfund sites or facing litigation over contaminated properties, the last thing you need is questions about your analytical data because of standard preparation errors. We've stepped in with labs who've had to retest entire batches after auditors flagged inconsistencies in their in-house standards documentation.
Food safety testing
The FDA's Pesticide Residue Monitoring Program and USDA's Pesticide Data Program don't mess around. Neither do major retailers implementing their own standards beyond government requirements. When you're testing to comply with CFR 40 Part 180 tolerance levels, you're often working in the parts-per-billion range where preparation errors multiply. One lab told us they spent $15,000 retesting samples after their in-house standards failed verification. Their customer, a national grocery chain, held shipments of produce worth tens of thousands while waiting for new results.
Cannabis testing facilities
State regulators in California, Colorado, Oregon and beyond have created a patchwork of required pesticide panels with action levels that differ by state. A failed test can mean destroying an entire batch worth thousands. We've seen labs lose their state licenses over calibration failures traced back to standards issues. In this high-pressure industry where clients push for passing results, your standards need to be beyond reproach when regulators come calling.
Drinking water analysis
When you're responsible for proving municipal water is safe under the Safe Drinking Water Act, there's zero room for error. EPA Methods 508, 525.3, and 527 require detection at microscopic levels where preparation variables become critical. Miss a contamination issue and it's not just about regulatory consequences - it's about public health. One municipal lab director told us how faulty standards led to retesting that delayed a water quality report, triggering public notification requirements and unfortunate news coverage.
Consumer product safety
The Consumer Product Safety Commission and various state regulations are cracking down on pesticide residues in everything from children's pajamas to imported furniture. Companies using your data make multimillion-dollar decisions about product recalls or shipping. When your testing determines if products violate CPSC regulations or California's Proposition 65, your standards can't be a weak link. A major retailer we now partner with once pulled products from 200 stores based on test results that were later questioned because of in-house standards preparation issues.
Research institutions
Your grant funding and publication credibility depend on reproducible results. When you're tracking pesticide degradation pathways or developing new analytical methods, inconsistent standards introduce variables that can invalidate months of work. Peer reviewers have no problem questioning key findings because of inadequate standards documentation. Delaying publication by months. With research budgets under constant pressure, you can't afford to waste time or resources on questionable data.

All standards are shipped in appropriate packaging to give you the longest shelf life.
Basics
Pesticide reference standards are high-purity, well-characterized chemical substances used as calibration and quality control materials in analytical testing. They provide a reliable reference point for identifying and quantifying pesticide compounds in environmental, food, water, and other samples. Each standard contains a precisely known concentration of specific pesticide compounds with documented traceability to ensure accurate test results.
Laboratories use pesticide reference standards for multiple critical purposes: calibrating analytical instruments, validating test methods, performing quality control checks, establishing detection and quantification limits, and ensuring regulatory compliance. They serve as the foundation for accurate identification and measurement of pesticide residues in environmental monitoring, food safety testing, drinking water analysis, and consumer product safety evaluations.
The production of high-quality pesticide reference standards involves sourcing ultra-pure starting materials, precise weighing using analytical balances in controlled environments, careful dissolution in appropriate solvents, and extensive verification testing. The process requires specialized equipment, controlled environmental conditions, and documented quality assurance procedures. Each batch undergoes rigorous testing to verify concentration, identity, purity, and stability before certification and release.
Pricing varies based on factors including compound rarity, concentration, volume, and whether it's a single compound or multi-component mixture. Single-compound standards typically range from $100-300 per vial, while multi-component mixtures designed for specific regulatory methods generally range from $300-700. Custom formulations may cost more depending on complexity. Our autoshipment program offers significant cost savings over these standard prices.
