More than 9 000 references are in stock and available within a couple of days.
For almost 95% of our products, the purity is higher than 97%.
Our catalogue is increasing each day as a result of new requests from our customers. To be as responsive as possible to our customers’ needs, A2S has set up a large network of suppliers, giving the opportunity to get original products at high purity levels.
These " A2S Standards " products are sorted in three families:
The NEAT products
A2S has chosen to offer molecules in unusual quantities. Whilst products are mostly proposed in 100 or 250mg, A2S also offers smaller packaging such as 1mg, 10mg and 25mg with a free exact weight. This exact mass is specified in the COA, and gives you the opportunity to create your own highly concentrated solution ready to be diluted. No waste or stock of raw material, you gain time and safety. CoA & MSDS Specimens
The single products in SOLUTION
In order to be as close as possible to the customers' requirements, our team has developed a procedure for preparing solutions that follow the steps - including control - that our own customers adhere to themselves. Our products are scaled (several times), diluted in solution, analyzed, compared to reference standards and then the final product is conditioned. At this moment, the final analysis takes place. After validation, the COA is linked to these results including spectral information. CoA & MSDS Specimens
The MIXTURES products
Our custom mixtures are a central and crucial element of our business. Their production follows long phases of internal improvement and development. On this basis, Analytical Standard Solutions has to deploy all the human and technical resources that are necessary to achieve the highest levels of certainty possible when manufacturing complex mixtures. A qualified team, perfectly controlled equipment (balances, micropipettes...) and powerful analytical instruments (LC-MS, LC-DAD-FLD, GC-FID, GC-MS…) are the key elements required for perfect mixtures. For maximum certainty, each mixture is made twice. Two different batches are controlled, compared and all peaks are identified with the utmost rigor. CoA & MSDS Specimens
