Tobacco moisture measurement with Near IR technology is long established throughout the world as accurate and reliable. Tobacco nicotine measurement on-line is of questionable value for a number of reasons.
GC, GC-MS, HPLC and HPLC-MS can all be used for tobacco nicotine determination in the laboratory. Near IR full spectrum analyzers utilizing PLS or other suitable chemometric treatments can also be employed in the laboratory on ground samples. The simplest and least expensive technique is GC. The levels of detection in a laboratory are in the ppm range rather than the % range that may be obtained using filter photometer NIR equipment on-line.
The difficulty with on-line nicotine measurement is that nicotine is not distributed evenly throughout the plant. The stem and the leaf and even within a single leaf contain significant variation in nicotine content. So, if you have more stem or less stem in the sample that alone shifts the nicotine measurement. Moisture equilibrates throughout the tobacco product, nicotine does not.
To indicate the accuracy of an on-line trend measurement of nicotine we need to determine the sample collection reproducibility and the sample analysis accuracy. The best way to do this is with 3 sets (or more) of double blind samples analyzed by a certified laboratory for nicotine content.
This means that two separate grab samples from the measurement point need to be collected at three different times. Hopefully the nicotine level is at a different level for each collection time. Otherwise it will be necessary to collect additional samples to create a range of nicotine levels.
When the samples are sent to the lab, the lab does not know which samples were collected at the same time, they are “blind” to this information to avoid bias in the analysis. The resulting data will determine how reliable the sample collection method is and the homogeneity of the samples collected.
Nicotine and related alkaloids/metabolites can be measured in the Near IR with chemometric treatments. The wavelength selection is the not the limiting factor in the measurement, it is the nicotine stratification throughout the plant. We believe that sample variation due to nicotine stratification makes a claim of absolute measurement on-line with photometers questionable at best.

Milford MA, June 30, 2016 – KPM Analytics announced today that it has acquired CHOPIN Technologies, based in France. CHOPIN is a world leader in providing quality testing solutions to the grain and flour markets. Throughout CHOPIN’s long history, the company has focused on solving difficult challenges faced each day by customers involved in grain and flour production. The company’s more than 100 employees work from the headquarters in France as well as from subsidiaries in China and the United States.
KPM Analytics (formerly Statera Analytics) was formed last year with the acquisitions of Unity Scientific and Process Sensors. The company’s premium brands provide instrumentation solutions for many industries and markets, from food quality and safety to environmental and agriculture.
“The addition of CHOPIN Technologies to the KPM Analytics group of companies demonstrates KPM’s focus on strong brands that bring a unique, application-focused set of solutions to customers. CHOPIN brings a particular strength in both the grain and flour production markets. This deep, market-specific technical strength is a perfect complement to the offerings of KPM’s other portfolio companies, Unity Scientific and Process Sensors. The combination of these 3 strong and well regarded brands positions KPM Analytics as a key provider in the global Food, Environmental, and Agricultural instrumentation markets.,” said Chris McIntire, CEO of KPM Analytics. “CHOPIN will continue to serve grain and flour customers as it has for decades, using the well regarded CHOPIN Technologies brand.” said Mr. McIntire.
“Joining the KPM Group is a great opportunity for CHOPIN Technologies,” says Marc Dolige, CHOPIN’s CEO, “Bringing effective and innovative solutions to our clients is and will remain our focus.” Marc Dolige will continue as CEO after the acquisition as will the entire CHOPIN management team. “We are thrilled to be adding Marc and his team to the group and look forward to continued innovation, growth and success” says McIntire.

Reverse Roll Coaters have a metering and applicator roll. Often there are 3 or 4 roll configurations. Coating is applied through the gap between the metering and applicator roll where the nip pressure and gap control the specific coat weight. The applicator roll runs in reverse direction of the web transferring the coating onto the web. Reverse Roll Coaters are capable of producing highly polished surfaces and are more expensive than some other coaters such as slot-die that can’t always achieve that level of polishing. If a Converter operates a Reverse Roll Coater a Cross Direction Web Profile System is a good investment to maintain uniform coat weight on high end products. The Guardian Cross Direction Web Profile System meets the application needs for film, foil and paper coat weight and moisture measurements on Reverse Roll and other coaters.
Sand Moisture Control is important in the manufacturing and processing stages. Giant sand piles may sit exposed to the weather rain or shine impacting the moisture content of the whole pile and external versus internal moisture profiles. It rained for 3 days and yesterday it was hot bright sunshine, then the exterior is dryer than the interior. Near Infrared Moisture Transmitters provide an immediate measurement of sand moisture on the belt. The transmitter is mounted between 8 and 18” (200 – 450 mm) above the product with an air purge of 3 – 10 psig to keep the sight lens clean. Large digital display, proportional analog output (4 – 20mA) and Ethernet communications are available.
Sand is sold by weight and specification, meaning that there is range of acceptable moisture level in the sand upon delivery. If the sand moisture exceeds that moisture level it can be rejected or purchased at a significant discount. If the sand moisture is lower than that specification the supplier is leaving money on the table by not adding water to increase the weight while still being in specification.
Sand moisture can be controlled by dryer temperature, throughput and re-moisturizing. Dryer Temperature adjustment may be used if a known incoming run of sand is high in moisture. As a practical process control option dryers have too slow a response time for minor variations that still need to be optimized to maximize efficiency (profit). Dryer throughput is the best control parameter as it can increase or slow throughput through the dryer based on moisture. When raw product is over dried or oven has over dried a moisture spray station may be triggered by the PLC. Moisture is money for Sand Suppliers. An upper level in-specification sand moisture allows End User to optimize for specific application and maximize profits for supplier.
