Step 1: squeeze a drop of colloidal material from the syringe and place it on a piece of white paper.
Step 2: if it is to form a watery infiltration halo, it may be hyaluronic acid, omeidine, cellulose, or collagen.
Identification method is: take a drop of hyaluronic acid on the left hand, and then hand in finger touch, over and over again in a few minutes after being most moisture evaporate, after finger touch or naked eye observation, visible there are sand granular crystal particles in the remaining residues, besides there is no other things, this is crosslinked hyaluronic acid, basic can confirm is really hyaluronic acid, can be used.
Step 3: extrusion products, on the plane glass plate, the watch again. As a result, after a night of moisture volatilizes, glass residual type composition analysis. If the residual is a type of composition, like the appearance of the "ice sand particle particle pile up, it must be hyaluronic acid. If it is" rice crust not opaque is scabby, usually ogilvy;if it's a soft yellowish soft film, it's usually cellulose. If it's a non-volatile oil, it must be silicone oil or paraffin oil.
Step 4: for solids is hyaluronic acid were identified, you can use digestion experiment method. Programs are: in 45 degrees of constant temperature water bath, will be of hyaluronidase solid particles in a container, 2 hours or so commonly, solid particles can degrade. If no degradation, it is surely not hyaluronic acid. (this is the point of the brine tofu, everything has its vanquisher.
The corresponding enzyme, which dissolves the corresponding compound).
