44 New 4-digit Density Meter Sets the Standard in Measurement Technology


The new DMA 1001 from Anton Paar shows that recycling old technologies does not work if you have the chance to create something unheard-of instead. The stand-alone density meter combines the completely new oscillating U-tube design with a newly developed measuring technology:


The patented Pulsed Excitation Method (AT516420 B1). This innovation delivers stable density results based on comprehensive knowledge of the oscillation characteristics. Thanks to U-View™ - a pin-sharp camera image of the measuring cell - the correct sample filling can be closely observed. Potential filling errors caused by inhomogeneous and viscous samples like crude oil and lubricants, bubbles, or particles are automatically detected by the FillingCheck™ feature. Up to 5000 results, including camera images and potential filling alerts, are stored in the instrument’s memory and ready for export and printing in various formats, ensuring perfect traceability for future quality inspections. Other features which simplify your daily work include the new unique one-point water adjustment.


DMA 1001’s rugged design allows for flexible placement, not only in the laboratory but also in production or storage facilities, providing the opportunity to save time by performing quick checks wherever you are. Furthermore, the instrument provides an intelligent condition monitoring


system that gives warnings and recommendations for required action in case of challenging environmental conditions. The new user interface is self-explanatory and can be operated via the 7” touchscreen with the look and feel of a smartphone.


All these features are included in the new DMA 1001, a 4-digit density meter which is fully compliant with USP <841>, Ph. Eur. 2.25, JP 17 2.56, and fulfils all requirements of FDA CFR 21 Part 11. It is the ideal entry-level model for laboratories in the pharmaceutical and cosmetic industries as well as in flavour and fragrance production.

In-House N2


/O2


Generation pays Dividends


Any company looking to invest in the latest high-purity, low-energy nitrogen and oxygen generators should look no further than the latest series from Hi-line Industries. Hi-line’s N2


/O2


bottled gas or bulk nitrogen/oxygen tanks ever again. Some applications may only require a purity of only 98% or 95%. When Hi-line designs an N2


generator of the same flow is 10 times cheaper. Hi-line N2


generator only runs when the process is calling for N2


generators utilise completely different control technology to traditional PSA N2 , and when no N2


generators use simple Pressure Swing Adsorption (PSA) technology to help ensure there is no longer any reason to pay for system, the cost of a 98% generator against a 99.99999% generators. A variable speed type technology is used, where the requirement is needed, the Hi-line generator goes on to stand-by. On start up, N2 at the


exact purity required is delivered due to a buffer/polishing tank along with a high purity storage vessel on the skid, meaning no down-time whilst waiting to reach purity.


Bottled gas is sold at high pressure, to enable smaller footprint, and regulated down. However, if your did need a 30 - 40 bar application, then Hi-line can add a booster to the skid to give you the exact pressure required at your process.


The cycle is continuously producing high-quality nitrogen, 24 hours a day. Used correctly, the CMS is fully regenerative and has a life span over 40,000 operational hours. Highlighting the potential savings on offer, a renowned food packaging company was spending over £120,000 having N2


Atmosphere Packaging) processes, the plant turned to Hi-line for an alternative solution. Hi-line was able to supply an N2 N2


only for the cost of compressed air; a huge saving year-on-year.


Hi-line is able to design bespoke generator systems for customers that ensure the lowest possible running costs and smallest footprint. Manufacturing takes place at the company’s new facility, which is three times the size of Hi-line’s previous headquarters. Hi-line is a member of the British Compressed Air Society, and proud to be part of the ‘Made in Britain’ campaign that promotes the best of British manufacturing.

Overhead Stirrers Combine Power and Intelligence


Wiggens offers overhead stirrers for stirring and mixing in the lab for both low and high viscosity. Safety, power and intelligence were again at the core of the development of this product range. The design focuses on the most essential aspects that produce overhead stirrers as reliable laboratory companions. The soft start, low speed guarantees a smooth and safe stirring process. Three different models are available in this series: each model has the same performance but with different manipulation experiences. Stable rotary knob and on-touch control can be implemented on different models if required. The stirring speed measures up to a maximum of 2,000 rpm with a torque of up to 70 Ncm. The WB2000-C can also be connected to the computer via a RS-232 cable for remote control and can be used as a stand-alone unit or, for instance, integrated in chemical reaction systems.


In addition, Wiggens have already prepared different packages to simplify customer ordering. This includes overhead stirrers, support stands, and stainless steel or PTFE impellers. For stir bearings, stir shafts and more detail on impeller types offered, please visit the company website.

Measuring pHe According to ASTM D6432


Excessive acidity in alcohol based fuels accelerates engine corrosion. Total Acid Number (TAN) accounts for all titratable acids regardless of their strength and is therefore not suitable to accurately predict the corrosion potential. pHe, on the other hand measures the strength of the acids present in the sample. Therefore, pHe is the better parameter for manufacturers to monitor the corrosion potential, maintain the quality of their product, and maximise profits.


Measurement of pHe in ethanol and ethanol fuel blends is standardised by ASTM D6423 and EN 15490. Application Notes describing the measurement of pHe are available free of charge from Metrohm.


The design of the sensor is crucial for accurate pHe measurements. The ASTM standard recommends a high leak-rate sleeve junction reference electrode and a large membrane glass measuring electrode, as these perform best for measurements of alcohol fuels. The Metrohm EtOH Trode is one of two sensor explicitly mentioned by ASTM D6432 as suitable for pHe measurements in ethanol and ethanol fuel blends.
