Coulter Counter Application in Copper Plating

A basic laboratory set-up to demonstrate the copper plating electrochemical process

A basic laboratory set-up to demonstrate the copper plating electrochemical process

The manufacturing of printed circuits often makes use of an electrochemical process known as acid copper plating. One of the potential pitfalls in this process is contamination of the electrolyte with particles, so manufacturers must keep a close eye on the numbers and sizes of any particulates present. Which is where a Coulter Counter comes in… Continue reading Coulter Counter Application in Copper Plating

Particle Size and Concentration in Oils

If you go to the Beckman Coulter website, www.beckmancoulter.com, look for the type of product in which you are interested – say Coulter Counter – and then click on ‘Literature’ in the right-hand column, you will open up a whole world of information. For example, I’ve just come across some application notes for use of a Beckman Coulter Multisizer 3 Coulter Counter in determining the size and concentration of particles in oils.

Evaluating Particle Content and Filtration Efficiency in Beer

What could be more important than testing the quality of beer? I have my own traditional method, which involves downing large quantities and then observing the effects, but as a scientist I am aware that there are many flaws in this approach. While looking through the Beckman Coulter website I recently came across an interesting paper on how to use a Coulter Counter in assessing the particle content of beer and evaluating the efficiency of the filtration applied to it.

Coulter Counter Used for Particle Counting and Sizing in Drinking Water

Drinking water

Here is a good example of how a Coulter Counter can be used. In this case, it’s to find out about the particulate content of water – which is essential information for those involved in water treatment and management.

Rules and Regulations

Rules and regulations

I need hardly tell you that scientific instruments and their uses are governed by a lot of regulation. I for one find it very reassuring to know that the manufacturer of my analytical instruments is well aware of the relevant legislation and has taken the necessary steps to comply. In the following article I would like to mention two key regulatory areas in relation to Coulter Counters: use of electronic records and compliance with current Good Manufacturing Practices (cGMPs).

Multisizer 3 Coulter Counter – Further Advantages

Coulter Counter - Multisizer 3

In my last post I gave a summary of the capabilities of the Multisizer 3 Coulter Counter from Beckman Coulter, but there was a lot more that I could have told you. For full advice on which Coulter Counter is best for your particular application, and why, you should talk to Meritics. In the meantime, I would like to tell you just a little more about what the Multisizer 3 can do. Continue reading Multisizer 3 Coulter Counter – Further Advantages

Multisizer 3 Coulter Counter

 

Multisizer 3 Coulter CounterYou will find a brief account of the Multisizer 4 Coulter Counter from Beckman Coulter elsewhere on this site. A similarly versatile and accurate instrument for particle sizing and counting is the Multisizer 3. Meritics will be happy to show you the differences and relate them to your particular needs.

A Bit of Coulter Counter History

The Coulter Principle was by no means the only discovery made by Wallace H Coulter (1913 – 1998) but it’s certainly the best known. This influential inventor, electrical engineer and businessman has no fewer than 85 patents to his name. Continue reading A Bit of Coulter Counter History
