Sample Preparation

Preparation steps are lab services too

In lieu of Sample Preparation workflow currently in Bika Senaite, the requirement is resolved by configuring Analysis Services as preparation steps and and sorting them at the top of lists, such as Sample Views, to be tended to first

Preparation Category

Create an Analysis Category, Preparation, and give it the highest sort  order of the categories, e.g. 10 in this example, the following Categories van be 20, 30, etc. to make it easier to insert categories later

Preparation Steps

Create the Preparation steps as Analysis Services in the Preparation - they too can be sorted in their Sort order settings, e.g. listing primary weighing first, then crushing and pulverisation steps (in a geochemistry lab analysing ore

Time stamping Preparation steps

To record the completion of the preparation step, and the user who did it, the Preparation steps have to have results captured and verified to proceed with the workflow

Some Preparation steps will have actual results recorded, like weight, but in most cases the user just needs to capture 'Done' and to do that we set up the steps Analysis Service with only 1 result option, 'Done'

Runtime

For preparation steps that include measurements, capturing it will also timestamp the action 

Preparation Worksheets

Since the Preparation steps behave like Analyses, they can be grouped on Worksheets and used where for example a whole batch of samples need to be dried or weighed
