Blank Material
This round cannot be purchased on its own, it is only available in conjunction with the similarly numbered pesticide residue round. Blank matrix samples are available to purchase with many of the proficiency test materials. Every effort has been made to ensure these do not contain the target analytes at concentrations that would compromise the nature of the proficiency test. Other analytes may be present. NB: Blank materials are not part of the proficiency test per se and so are not included in our scope of accreditation to ISO/IEC 17043.
Tomatoes are widely consumed across the globe and are key ingredients in many cuisines all over the world. This ensures high demand year-round which can challenge suppliers to satisfy profitably.
Pesticides used within farming processes offer a reliable way to ensure high quality produce is being offered to manufacturers and in turn consumers. This is only the case when good farming practices are adhered to. As pesticide usage increases high levels of pesticide residues can be passed to the consumer through the tomatoes leading to increase exposure over normal, safe levels.
This proficiency test is specifically for a range of pesticide residues that are generally determined using specific single-residue methods. Most pesticide residues are determined using multi-residue methods, that is ones in which potentially hundreds of compounds can be measured with a single extraction protocol and instrumental method, based on multi-stage mass spectrometry. However, some pesticides are not very amenable to the generic multi-residue approach and still require more specific extraction regimes and chromatographic-mass spectrometric approaches.
The presence of metals in food is of particular concern due to their toxicity. These naturally occurring chemicals can occur as residues in food by a range of mechanisms such as their natural presence in the environment or contamination during food processing and storage. Their accumulation in the body can lead to harmful effects over time and their presence in foodstuffs is strictly regulated.
Blank materials from Fapas make use of real food matrices to provide the key insights into your routine testing abilities you require. These can be used to maintain the level of accuracy required to satisfy both your customers and regulators of your testing capabilities.
