We’ve all experienced the discomfort of unexpected company. You get the phone call where someone lets you know they’ll be stopping by shortly. You rush to put the clutter in your house away in random cabinets and drawers. You sweep the dust and dirt behind a dresser or under a rug. You mask the disorder by making it look good temporarily. If you’re not careful, a process calibration of a pH measurement could be doing the same thing. You could just be forcing the measurement to look right temporarily. However, there are better practices to... Continue reading

We here at M4 Knick love three things: being in love, having a good laugh, and analytical instrumentation of course. So, we’ve got you covered this Valentine’s Day. We created a list of 10 swoon-worthy pickup lines and memes to impress your next date— liquid analysis style.
Ok, Ok, it’s a little low-brow, but hey the analytical equipment industry is rampant with terminology just waiting to be a turned into pickup lines. Seriously, who can resist a good pH probe joke?! We sure can’t.
Sour water is a byproduct from steam stripping of crude oil in a variety of refinery distillation processes. Sour water treatment removes ammonia and hydrogen sulfide from water, both are damaging to overhead condensers and other process piping and vessels. The flash drum removes light hydrocarbons from the sour water before the water moves... Continue reading

Check out the predictions these liquid analytics professionals have provided regarding the impact digital sensing technology will have on predictive maintenance, asset management, product quality, reporting and safety in 2019.
A common question I get from customers about pH measurement is "How accurate is my sensor?". You'd think there would be a straightforward reply like 0.25% of range or 0.5 pH of the span. Unfortunately, it's difficult to provide a definitive answer to this question. As a matter of fact, it's rare to see an accuracy specification for most process pH electrodes. When you do see one, there are a number of exceptions. This is because there are many uncertainties and potential measuring errors, such as:Buffer solution degradation or contaminat...

Are you spending a lot of money on pH sensors? Like most process instruments, proper installation and maintenance play a significant role in determining the effective life of your sensor. In this writeup we address the top four things you can do to extend the life of your pH sensors through proper maintenance. Continue reading
The SE 655 Memosens toroidal conductivity sensor is ideal for measurements in liquids with suspended solids and high conductivities. This corrosion resistant sensor is constructed of PEEK in a smooth, easy-to-clean design and comes with an integrated 3m cable. The SE 655 is highly accurate and has a low risk of contamination because of a large sensor opening.
The robust sensor design and construction, along with t... Continue reading
The bleaching process is very challenging for pH electrodes due to plugging and chemical attack. The pulp consistency can easily reach 10% and quickly plug the junction of the many pH electrodes. The pH range of the pulp changes drastically several times during bleaching. This alternating chemical process yields extreme pH values of around 3.5 in the chlorine dioxide (ClO2) stage and a value of around 11.5 during the c... Continue reading
The SE 554 Memosens pH sensor is ideal for use in liquids with suspended solids and high ionic strength. This low-maintenance sensor is constructed using Alpha pH glass, 2 open hole junctions & a solid polymer electrolyte with high KCl concentration. These features provide stable performance and long life in the most difficult applications.
The integrated NTC 30K temperature element assures that all pH measurements are accurat... Continue reading
Liquid analytical measurements in sugar refineries are challenging due to the processes needed to convert the sugar contained within the sugar beets into a concentrated liquid called thick juice.
Critical steps in the sugar purification process are 1st and 2nd carbonation. Continuous pH monitoring is needed to ensure the efficiency of the carbonation stage. Because of the potential for excess... Continue reading
