1. What is C18 powder?

- C18 (Octadecylsilane) is a bonded silica phase commonly used in the sample clean-up procedure. It can adsorb non-polar and semi-polar compounds from the sample, helping to remove fats, oils and other interfering substances that can affect the analytical results.

- Trong SiliaQuick™ Bulk C18 (23%C), a 23% C (carbon) ratio shows the strong adsorption capacity of this product, helping to raise sample clean-up efficiency, especially in food samples with a high fat content.

2. Outstanding features of SiliaQuick™ Bulk C18 (23%C)

- High cleaning efficiency: with a 23% C content, SiliaQuick™ Bulk C18 (C18 powder) can remove unwanted substances from the sample such as grease, lipids and other non-polar compounds, ensuring the sample is clean and ready for analysis.

- Suitable for the QuEChERS method: This product is optimised for use in the QuEChERS procedure, saving sample-preparation time and improving the accuracy of the analytical results.

- Mass 250 g: With this bottling, the product provides enough quantity for many uses, suitable for laboratories processing many samples at the same time.

- High quality: Manufactured to a high quality standard, SiliaQuick™ Bulk C18 ensures no sample contamination and brings high reliability in analysis.

- Wide application: The product can be used in many different sample types, from vegetables and fruit, meat and fish to dairy products, helping to increase flexibility and efficiency in food analysis.

3. Applications of SiliaQuick™ Bulk C18 in QuEChERS

- During pesticide-residue analysis in food, such as vegetables or fruit, fats and oils can interfere and reduce the accuracy of the analytical results. SiliaQuick™ Bulk C18 is used to adsorb these compounds, clean the sample and prepare it for the next analytical steps by gas chromatography (GC) or liquid chromatography (LC). This helps improve the sensitivity and accuracy of the measurement considerably.

- SiliaQuick™ Bulk C18 (23%C) for QuEChERS 250G (C18 powder) is a powerful and effective solution for residue-analysis and food-safety procedures. With outstanding sample clean-up capability, this product helps increase the accuracy and efficiency of the QuEChERS method, and is the ideal choice for laboratories and researchers who need to ensure food safety in the analytical process.
