Math Models for Non-Linear Chemistries

Type

Formula

Model #1

Math Model #1 is the four-parameter log-logit function most
commonly used with reagents that use antibodies.

Sample values are determined using the calculated curve parameters
and the math model. Values may be calculated directly as this model
can be solved for concentration.

Model #2

Math Model #2 is a five-parameter logit function.

This function cannot be solved directly for concentration. The
instrument uses an iterative method to determine the sample value.

Model #3

Math Model #3 is a five-parameter exponential function.

This function cannot be solved directly for concentration. The
instrument uses an iterative method to determine the sample value.

Models #4
through #7

These Models are reserved for future development.

Model #8

Math Model #8 is an alternative to model #2, the five-parameter logit
function.

This function cannot be solved directly for concentration. The
instrument uses an iterative method to determine the sample value.
