Dissolution

Fiber optic dissolution is the quicker, more reliable alternative for large or difficult data sets. 

 

Traditional dissolution testing is conducted by manually removing samples from dissolution vessels and bringing the samples to a UV spectrometer or HPLC for testing. With fiber optics, real-time drug release level is determined in-situ or in the vessels without sample removal. The labor-intensive manual sampling procedure is eliminated and the testing procedure is simplified.

 

It is more economical because consumables for sampling, such as pipettes, syringes, sippers, tubing, and filters, are not needed. In addition, fiber optics can generate more frequent data points and produce a more detailed dissolution profile, which may be beneficial for showing a method’s discriminating ability.

 

With over 15 years on the market, Pion’s Rainbow fiber optic technology is the benchmark of reliability. Ten out of ten of the top pharmaceutical companies use Rainbow fiber optic technology for their in-situ UV monitoring needs. It has programmable data collection of the entire UV Spectra as fast as every 2 seconds from any type of dissolution vessel, vial or chamber. Rainbow fiber optic technology is a flexible and reliable tool for determining the rate of release of a drug substance over time.

AuPRO™ 5.1
The Latest in Pion’s Comprehensive Monitoring Software

 

AuPRO™ 5.1 brings Pion’s fiber optic users advanced tools for the analysis of kinetic solubility and dissolution.  Addressing the needs of today’s drug development scientists, AuPRO™ 5.1 provides exciting new ways to analyze data:

 

  • Implementation of ZIM (Zero Intercept Method) for Dual Component Analyses—An application of second derivative spectroscopy to account for the presence of two different absorbing components within the same matrix
  • Two Component Concentration Monitoring—Enabling multiple standard curves to be utilized for the analysis of dual component systems
  • Spectral Shape Analysis—Detection of Spectral Changes Between Standard and Sample Spectra due to pH, degradation, or other chemical in situ phenomena
  • Media Change Manager with Volume Tracking vs. Time—Allows for a single data file to have multiple media addition steps while accurately calculating concentration and % dissolved
  • Reference and Blank Channel Designation—Accounts for changes in molar absorption related to peak shifting, media change, or any other chemical change in a drug substance
