PRODUCT DESCRIPTION

FLASH is an advanced transient absorption curve fitting software complementary to the L900 package. Fitting complex kinetic decays only takes a few seconds with FLASH.

The program combines a user-friendly graphical interface with an advanced least-square minimisation algorithm fitting to models for 1st, 2nd, and combined 1st and 2nd order kinetics. Traces can be fitted simultaneously with linked parameters using global analysis.

FLASH is directly compatible with L900 data as well common formats such as ASCII. Results can be exported in a variety of text and image formats for ease of publication.

PRODUCT IMAGE

Analysis options include:

  • Analysis of first order kinetics with up to four exponential terms
  • Global analysis of first order kinetics
  • Analysis of second order kinetics
  • Global Analysis of second order kinetics
  • Analysis of mixed first and second order kinetics
  • Global Analysis of mixed first and second order kinetics
  • Calculation of parameter confidence intervals by support plane analysis

Software Features

Batch Fitting

Batching Fitting Screenshot

A set of TA data (in this case 2nd order kinetic traces) can be fitted and displayed simultaneously in FLASH.

Global Analysis

Global Analysis

Global analysis allows linking parameters across the full set of TA traces to analyse.
