Welcome to Chemios!

The Chemios Framework is a simple, open-source (i.e. FREE) software package for laboratory automation and monitoring.

It is easy-to-use and extensible. It currently works with pumps, spectrometers and temperature controllers. And, the list of equipment will continue to grow.

The framework is written in python (the unoffical language of science) and actively maintained. It works with pumps, spectrometers and more.

chemios.pumps

chemios.spectrometers

Chemios Ocean Optics Module

class chemios.spectrometers._oceanoptics.OceanOptics(spectrometer_model, seabreeze)[source]

Class to define the spectrometers

spectrometer_model

Model of the spectrometer (e.g., FLMS02673)

Type:str
seabreeze (

obj:): Seabreeze.spectrometers object

absorbance_read(integration_time, scans_to_average, filter=0, normalized=False)[source]

Function to read the UV data from the spectrometer Stores the normalized absorbance and flourescence data into Spectrometer Object

Parameters:
  • integration_time (float) – Integration time in microseconds
  • scans_to_average (int) – Number of scans to average over
  • filter (int, optional) – The starting point for the Spectrum (e.g, start from the 300th data point). Defaults to use the whole spectram
  • normalize (bool) – If true, absorbances will be normalized to the maximum absorbance. Defaults to false.
Yields:

Numpy array with first column as wavelengths and second column as absorbance
read_spectrometer_raw(integration_time)[source]

Function to print the raw data from the spectreomter

Parameters:integration_time (float) – Integration time in microseconds
Yields:Numpy matrix with first column as wavelengths and second column a intensisties
store_blank(blank)[source]

Method to save blank intensisties

Parameters:blank (array) – Two column array of wavelengths and intesities
store_dark(dark)[source]

Method to save dark intensisties

Parameters:dark (array) – Two column array of wavelengths and intesities
