dls-analysis

Analysis of Dynamic Light Scattering (DLS) measurements from Malvern Panalytical Zetasizer instruments.

Installation

npm install dls-analysis

Usage

import { readFileSync } from 'node:fs';

import { fromZmes } from 'dls-analysis';

const arrayBuffer = readFileSync('measurement.zmes').buffer;
const measurements = await fromZmes(arrayBuffer);

Each measurement contains the following variables:

| Key | Label | Units | Description | | --- | --------------------- | ----- | ------------------------------------ | | x | Particle diameter | nm | Particle sizes | | y | Intensity | % | Particle Size Intensity Distribution | | v | Volume | % | Particle Size Volume Distribution | | n | Number | % | Particle Size Number Distribution | | w | Molecular weight | Da | Molecular Weights | | d | Diffusion coefficient | µm²/s | Diffusion Coefficients | | r | Relaxation time | µs | Relaxation Times | | f | Form factor | | Form Factor |

Metadata includes Z-Average, Polydispersity Index, operator name, dispersant and material properties.

Settings include instrument manufacturer, model, serial number, detector angle, laser wavelength, temperature, and more.
