Over the last 10 years, kinetic LAL testing has become the most powerful quantitative technique for highly sensitive & wide dynamic range endotoxin measurement. Unfortunately, number of problems inherent in the system, such as questionable signal specificity, signals mixed with hydrodynamic disturbances (i.e., kinetic turbidimetric), and signal drift, have weakened its utility and reliability, which can result in frequent retests and OOS.

DQ (Design Qualification) of a test system is a rare happening in the laboratories. IQ, OQ, and PQ practices are routinely expected, but DQ is another matter. What is DQ? DQ is the built in capability, let us say the worst-case-scenario specification, of a test system. For example, signal resolution, signal accuracy, and signal reproducibility are highly dependent on the A/D resolution and the capabilities of the hardware-software design, such as robust kinetics. Therefore, what should the specification of my test system relative to the worst-case-scenario I have to meet? PyroDoQ will be able answer your questions.

PyroDoQ is based on highly accurate mathematical modelling of LAL-endotoxin kinetic reaction. The model was evaluated & verified against large number of actual - over 100,000 - test results.

Key Features

  • Simulation of a LAL-kinetic test conditions - LAL-kinetic curves can be generated by the user relative to the following parameters: endotoxin concentration in EU/ml, noise in dB, and outliers,
  • LAL-kinetic model characterization - detailed information is provided to understand the foundation of the simulation model,
  • EndotogramTM and EndotographTM - improved interpretation of LAL-endotoxin kinetic reaction pattern for signal specificity,
  • Robust kinetics simulation - simulate the kinetic scan and observe the results in 2D or 3D diagrams,
  • Method development simulation & uncertainty analysis - method development process & uncertainty in measurement are supported by statistical analysis & graphical visualization, including best practices,
  • SQC modeling of analytical parameters - evaluate the dependence of critical quality criteria, such as PPC recovery, relative to the behavior of standard curves, including, slope, intercept, and standard deviation,
  • Knowledge about LAL-kinetics - update & improve your knowledge about LAL-endotoxin kinetics; extensive HTML based information with embedded simulation provides a rich knowledge base for better understanding of method development requirement.


PyroDoQ offers rich set of models for DQ & method validation of kinetic turbidimetric & kinetic chromogenic testing for broad set of applications, including:

  • Pharmaceutical & biotechnology,
  • Medical device,
  • Clinical, and
  • Environmental.

You will be able to determine, which measurement system is suitable for your testing requirements at the lowest possible cost.
