Paracetamol,isopropylphenazone,and caffeine in Melton tablets were determined by HPLC with a UV detector at 254 nm in a C18 column and a mobile phase of methanol + water(60+40).

Preparation and clinical application of diclofenac sodium gel;

Study on transdermal absorption effects of four diclofenac sodium ointments by HPLC;

The determination of Diclofenac Sodium in ophthalmic solution by UV-spectrophotometry was reported and its stability by HPLC was studied.

Methods Injecting 5% bromogeramine solution 4-6ml (200-300mg) into the amniotic cavity for induced abortion in 200 cases.

An experimental study was conducted to investigate the synergic sterilization of bromogeramine combined with glutaraldehyde.

Results:Bromogeramine of any concentration had no effect on Pseudomonas aeruginosa.

In an acidic Britton-Robinson buffer solution, benzalkonium bromide (dodecyldimethyl benzylammonium bromide, BB) can react with nucleic acids such as ctDNA,hsDNA, sDNA and yRNA, which leads to the great enhancement of resonance Rayleigh scattering (RRS), and the maximum RRS peak is located at 470 nm.

This paper deals with the in\|chamber toxicity test on the zoaeae of Chinese mitten crabs to obtain the safe concentration of benzalkonium bromide against zoaeae.
