Deformulation
Chemir Analytical Services is the industry leader in the deformulation of products and materials. Also known as reverse engineering, deformulation is the separation, identification and quantitation of ingredients in a formulation. Our experienced chemists have performed deformulations on many types of medical devices, including implants, stents, tubing and more.
Deformulation analysis uses instrumental techniques and conventional extraction methods to identify and quantify the components of a complex mixture. Although we do not guarantee a "cookbook recipe", our analysis, in most instances, identifies the chemical class of major and minor components. A computer library search is also performed when needed to locate the trade names of similar, commercially-available materials.
We have successfully deformulated a variety of products used in medical devices, such as:
- Textiles
- Adhesives (PSA, hot melt and water borne) and sealants (epoxy, PU, silicone)
- Rubber products (natural rubber, EPDM, TPE, Neoprene, SIS, SBS, NBR, EVA, PUR, silicone and more)
- Plastics (PP, PE, PMMA, Nylon, PU, flexible and rigid PVC, copolymer and blends, degradable PP and PE)
- Specialty products (multiple layer films, high temperature engineered products)
- Composites (glass reinforced, carbon or graphite filled, Kevlar fiber reinforced and more)
Reverse engineering of medical device products may be used for:
- Competitive product characterization
- Identification of batch to batch variations
- Comparative analysis of "good" and "bad" samples
- Patent infringement or trade secret investigations
