1. What is the QuEChERS method?

- QuEChERS is short for "Quick, Easy, Cheap, Effective, Rugged, and Safe," roughly translated as "Fast, Easy, Cheap, Effective, Sustainable and Safe." This is a popular technique in the analysis of pesticide residues, toxins and other contaminants in food.

- This technique was developed in order to optimise the extraction, enrichment and sample clean-up process before analysis by chromatographic methods.

2. Role of SiliaQuick™ Primary Secondary Amine nec

- SiliaQuick™ Primary Secondary Amine (PSA powder) is an essential adsorbent component in the QuEChERS method, used to clean food samples and remove unwanted compounds such as organic acids, fatty acids, sugars and other interfering substances. Form nec of the product (non-endcapped) means the product has higher efficiency in removing polar substances, helping to improve the analytical results.

3. Outstanding Characteristics

- High quality and purity: SiliaQuick™ PSA is manufactured to a high quality standard, ensuring no sample contamination and providing reliable results.

- Optimised for QuEChERS: This product is manufactured especially to optimise the sample clean-up process in QuEChERS, minimising sample-preparation time and enhancing the sensitivity of the analytical method.

- Mass 250 g: With this mass, the product provides enough for many uses, suitable for laboratory scale or research projects that need to process a large number of samples.

- High flexibility: SiliaQuick™ PSA can be used for many different sample types, from vegetables and fruit to dairy products, meat and fish, helping to increase the applicability of the product in food analysis.

4. Practical Applications

- During pesticide-residue analysis in fruit and vegetables. For example: PSA powder is used to adsorb and remove interfering substances such as fatty acids and sugars. After PSA is used, the sample is cleaned and prepared ready for analysis by techniques such as gas chromatography (GC) or liquid chromatography (LC), ensuring accurate and reliable results.

- SiliaQuick™ Primary Secondary Amine nec for QuEChERS 250G (PSA powder) is an advanced and effective product, playing an important role in optimising the food-analysis process by the QuEChERS technique.

- With high reliability, ease of use and wide applicability, this product deserves to be the leading choice for laboratories and researchers interested in food-safety analysis.
