DML 3000 User Manual

3.10

Detector

The DML 3000 uses a single PMT to measure chemiluminescence of the microplate

wells on a 96-well microplate. It leverages both photon-counting and current-

measurement modes to optimize the dynamic range of the DML 3000.

A light detector using a PMT can be characterized by the following parameters:

Background signal

Efficiency

Sensitivity

Dynamic range

Linearity

Spectral response

3.10.1

Background signal

The background signal can be divided in two components:

A constant (baseline) component

A statistically variable (noise) component that is different for each individual

measurement

The background signal in the photon-counting mode is automatically checked at the

start of each microplate measurement. In the current-measurement mode, used at

high RLU levels, the background level is subtracted from each reported measurement.

3.10.2

Efficiency

Efficiency is the response (detector output signal) versus the input signal (light

intensity). Efficiency is the gradient of RLU versus gradient of light intensity.

3.10.3

Sensitivity

Sensitivity is related to both background signal and efficiency. Sensitivity is directly

proportional to efficiency and the background signal is inversely proportional (higher

background results in lower sensitivity).

Sensitivity describes the lowest intensity of light that can be detected as different

from background. Sensitivity is usually measured using the amount of a luminescent

substance the DML 3000 is able to detect and clearly distinguish from background

noise.

3.10.4

Dynamic range

Dynamic range is the relationship between the lowest and the highest signal that the

detector is able to quantify. The dynamic range for the DML 3000 is 10 to 5x10

RLU.
