Products from the A2S brand


Analytical Standard Solutions, under the A2S brand, offers a wide range of products : more than 1 500 references are hold in stock and available in a couple of days. Our catalog is increasing by an average 50 products a month. To reach that goal, A2S has set up a large network of suppliers, giving the opportunity to get original products at high purity levels.

These " A2S Analytical Stantdards " products are sorted in three families :

  

  •  The NEAT products : A2S chose to offer molecules in unusual quantities. When such products are mostly conditioned at 100 or 250mg, A2S also proposes smaller packaging such as 1mg, 10mg and 25mg. Moreover, for each product is specified in the Certificate the exact scaled quantity present inside the vial. In the case of 1 and 10mg conditioning, this can allow our customers to fill directly the vial with a chosen solvent to obtain the desired cocentration, which is a gain of time and safety.

  •  The products in SOLUTION : our process is made to be the same as our customers'. In order to be as close as possible to their requirements, our team has developed a procedure for preparing solutions that follow the steps - including control - that our own customers impose to themselves. Our products are scaled (several times), put in solution, analyzed, compared to reference standards and then the final product is conditioned. At this moment, the final analysis tooks place, the spectral information is extracted and the Certificate of analysis is created with these results and no other. No surprise ! When the results are satisfying, the product is shipped. Otherwise, the process aborts and starts again from zero. See an example of our Certificate of analysis

  •  The MIXed products : our mixtures are a central and crucial element of our customers' activities. Their making follows long phases of internal imrovements and developments, and each piece of instrumentation (LC-MS, GC-MS...) has its own associations. For our customers, they are also an essential tool to achieve their control tasks. On this basis, Analytical Standard Solutions had to deploy all the human and technical resources that are necessary reach the highest sureness possible when manufacturing complex mixtures. A qualified personel, perfectly controlled equipment (balances, pipettes...) and powerful analytical instruments are the inevitable elements required for faultless mixtures. For maximum sureness, each mixture is made twice. Both batches are controled, compared and all different peaks are identified with the utmost rigor. See an example of our Certificate of analysis
