How to measure salt in potato chips using an automatic titrator

Mon, Oct 12, 2015 @ 04:22 PM


There are still many who test salt content by hand and so the thought of using an automatic titrator might sound intimidating.  It's not. Really.  So we thought it would help if we made some videos to explain some of the basic steps involved and show for those who have never seen one what a titrator looks like.  To be sure there are many capable titrators that can do the job so don't get completely caught up in which one is best but think more about the benefits of automating a test that is repeated many times daily.  

In the following videos we provide a step by step look at how a sample (potato chips) would be prepared and tested using an automatic titrator with the help of a 6 position sample changer.  

VIDEO DEMONSTRATION:  Testing Salt in Potato Chips with Titrator


WHAT YOUR GOING TO NEED IN ADDITION TO THE TITRATOR:

1. Silver Nitrate; 1.0 or 0.1 normal strength (This is the titrant that you will use)

2. Combined silver electrode (it's a silver and pH electrode combined)

THINGS YOU SHOULD KNOW:

1.  How do you currently prep your sample.  This process should not really change.  Sample prep is important though and should be considered.

2. Know the ingredients of your sample.  You should have a pretty good idea about the types of chlorides and sodium that may be found in your sample.
