Some pointers and ideas to help you devise a method and practical for the new unit 19 applied science unit.
This practical is one of the 4 options for assignment B. I know that the use of IR for quantitative analysis is uncommon, but it can be done.
Find attached a journal article of a similar experiment and a short outline of a method (word doc). Journal is obviously not my own work, I have just uploaded these to help centres devise their own methods for this assignment.
I hope this is helpful for you.
Please take a look at my other resources :-)

I created YouTube videos with instructions and activities in, a demo of the practical and results that students can use to analyse. I also explain and guide them through the calculations:
Risk assessment: what and how to and guides students through how to write their own and what to include https://www.youtube.com/watch?v=6XRQfdqygTk&t=10s
Practical: includes explanation, demo, activities throughout - how to write up and structure a lab report and how to tabulate results and do the first lot of calculations https://www.youtube.com/watch?v=8NqUFSO5Ck0&t=199s
Method attached
Sample results for PAG 10.3 attached in Excel file

Here are 4 sets of sample results that students can use to practice the calculations or in case they lost their results.
There is also a video which they can follow along with as a guide while they do their calculations, which explains each step: https://www.youtube.com/watch?v=kb3f_9rxcac
The other document is a task list, which tells the student step by step how to structure their report (what headings in which order), where to put their results and where to follow along with the video :)
This resource is ideal for an online lesson or cover lesson task.
Method, with link to useful YouTube video demonstrating the practical. Practical-based Qs testing students understanding of the steps in the method, answers at bottom.
Slightly different method for stretch and challenge - can run more than 1 chromatogram simultaneously and some extra Qs at the bottom relating structure to Rf value.
