Automatic Sampling: Helping The Dairy Industry Lead The Way In Food Safety

Posted by John Powalisz on 7/26/17 2:00 PM

In 2016, food recalls surged 22% to 764, with many tied to the dairy industry. Contaminated dairy products can be linked to consumer illness, with the potential to permanently damage a dairy’s brand. How can milk and milk ingredient processors turn the tide, while complying with new and expanding regulations? Automatic sampling can help ensure that milk, cheese, yogurt and ice cream producers not only comply with the latest regulations, but also avoid harmful and expensive recalls that can lead to brand damage – or worse.

What To Know About Cycle Chemistry Sampling Equipment

Posted by John Powalisz on 6/28/17 2:00 PM

The power industry has changed drastically, and the ability to start up quickly and generate reliably and economically are no longer luxuries, but requirements. That puts more pressure than ever on your steam and water sampling system. Here’s what you need to know to minimize the adverse effects of cycling on chemistry results and streamline busy start up times. This information was originally presented by John Powalisz at the 37th Annual Electric Utility Chemistry Workshop, held June 6-8 in Champaign, Illinois.

Steam and water sampling is a key component of a successful chemistry program in cycling power plants. It helps protect both equipment and plant personnel, while ensuring maximum output, helping identify and predict failures, and helping start up the unit faster.

How to Understand the Cation Resin Lifespan

Posted by John Powalisz on 4/19/17 4:16 PM

Cation resin can last a few days or several months, and it can be difficult to predict the lifespan even in ideal conditions. So how do you know if your resin is still functional at any given time? What does it take to prolong the life of resin – and how do you know when it’s time to refill or regenerate it? It all starts with understanding the cation resin lifespan and the many factors that affect it. Read on so you’ll never get caught with depleted resin again.

How Sweetener Sampler Eliminates Potential Contamination

Posted by John Powalisz on 4/5/17 11:00 AM

Just as trusted ingredients are critical to a food production operation; automated sampling is a critical part of any ingredient manufacturer’s processes. A nutrition and health food ingredient supplier to the food, beverage and dietary supplement industries needed to analyze representative samples of its product: polydextrose, which is a sweetener ingredient used in bakery products, beverages and baby food.

This food supplier’s customers requested it use modern biological contamination sampling techniques of its product to ensure quality.

How to Select an Aseptic Sampler for Food Production

Posted by John Powalisz on 3/29/17 10:30 AM

In the food industry, aseptic equipment is vital to ensure food safety. That equipment includes aseptic samplers used by quality control personnel to easily and safely sample liquids from closed systems such as food and beverage process lines and vessels. Aseptic samplers guide the product through a hermetically sealed system directly into a bottle without contact to the environment.

Refinery Implements Best Practices in Crude Oil Sampling

Posted by John Powalisz on 1/4/17 10:30 AM

Within the oil and gas industry, hydrocarbon liquids such as crude oil, condensates, and oil and water mixtures must be sampled to yield representative samples for analysis. The resulting data is used for quality control, to determine product properties and composition, and for fiscal calculations, allocations and loss control.

In addition to complying with custody transfer standards such as API 8.2 and ASTM D 4177, the advantages of representative sampling include:

  •  Higher return on investment
  •  Better loss control
  •  Lower operating costs
