pH Workshop

phThe course will be facilitated by Nelson-Jameson’s in-house pH expert, Steve Zdun. The workshop is perfect for an array of food and beverage industry producers to learn more about the basic principles of successful, and effective pH analysis in the processing environment.

Participants will garner insight into a host of topics, including: sample preparation techniques, choosing the best electrode/meter for the job, the importance of Automatic Temperature Compensation, calibration techniques, cleaning/maintenance procedures, and basic trouble shooting. Steve has also planned time for a question and answer session, as well as one-on-one consultation. By the end of the session that runs from 9am-12pm, class participants will leave with a constructive base of information to take with them into their facilities, as well as receive a certificate of course completion.

Sign up for the course by giving us a call and requesting item #333-3333. Our Customer Service Representative will take down your name, title, and organization. Cost for the course is $75. Register early as space is limited!

Tech Tip: Tips for Smooth-Running pH Testing

1010001

Pick the right meter. A pH meter with more than minimum requirements may be the better option. Product requirements and regulations change with time. Meters with advanced features will allow for a wider range of testing and documentation of results.

Know the basics. The meter’s algorithm and displayed value expresses the amount of potential difference between the electrode’s reference to a sample being tested. During the process of electrode equilibrium (or end-point), a blockage or slowing of an electrode’s reference junction can impact the electrode’s ability to perform its task.Remember electrodes need to be rinsed and blotted before each test.

Maintenance is critical. Periodic and proper cleaning is required. Protein and other contaminants can build up on the electrode reference junction or sensing areas, often resulting in a longer time to endpoint. Cleaning solutions specifically designed for differing electrode styles are required.

Tech Tip: Conditioning New pH Electrodes

3580100Many pH electrodes are shipped with the electrodes moist. Prior to using your electrode for the first time it needs to be conditioned. While it is always best to refer to the manufacturer instructions for proper electrode conditioning, below are three common recommended steps for conditioning your electrode:

1. Remove the protective cap or bottle from the bottom of the sensor and rinse the electrode with distilled or deionized water and blot with a Kimwipe.

2. Place the electrode in a beaker containing one of the liquids listed below (in order of ionic ability to condition the electrode.) Soak for 20 minutes.
• 3.0 M KCI
• 4.0 pH buffer
• 7.0 pH buffer

Note: Never condition or store a pH electrode in water – long term exposure to purified water will damage the special glass membrane.

3.  After conditioning the sensor for 20 minutes, rinse the electrode with distilled or deionized water and blot with a Kimwipe. The electrode is now ready for calibration and to measure pH.

The Complete Package

MP900216058In our area we get a lot of requests for “everything needed to set up a  lab”. Without information about the products being manufactured and specific tests to be run, this question is virtually impossible to answer. Even though meat, cheese and catsup all require accurate pHs each product requires a different combination of meter, electrode, cleaning solutions, buffers and temperature compensation. Of course location of test and capability of analyst have to be taken into account as well.

The same is true for salt, somatic cell counts, butter fat etc. etc. Unlike most of our competitors who sell individual components of tests, we sell test systems. We have this advantage because of our focus as a company on specific markets. This allows us to acquire knowledge necessary to take this approach to marketing products.

The other component of Nelson-Jameson’s success in selling specialty products suited to customer applications, are more basic qualities typical of our employees. These are interest in our customers well being combined with good questioning and listening skills. Without these traits alignment of products with applications would be disastrous failures. In all our interactions with customers from receiving telephone calls, attending our exhibits at trade shows and making sales calls, these skills make the difference between contented customers who keep coming back and quiet phones, closed doors and really boring trade shows.

When starting up a new lab, let us help – call our Technical Sales Staff at 800-826-8302.
