Expect More with New Viscometer Series
Anton Paar launches an entire SVMTM series for easy, accurate and fast measurement of viscosity. These viscometers give you more parameters than any other kinematic viscometer on the market. There is an SVMTM for every application: ranging from lubricating oils, used oils, crude oils, heavy fuels, distilled fuels to vegetable oils and fats.
The innovative double-cell design of SVM 4001 allows for simultaneous measurements
at 40 °C and 100 °C. As each of the measuring cells also contains an integrated density oscillator, density measurements according to ASTM D4052 at each temperature are simultaneously performed. The minimum sample volume needed for Viscosity Index determination and the density measurements is only 2.5 mL. The Viscosity Index results according to D2270 as well as API calculations are automatically shown on the touchscreen.
Moreover, SVM 4001 allows for simultaneous determination of viscosity and density at any two temperatures between 15 °C and 100 °C. This SVM model also provides viscosity-temperature extrapolation according to ASTM D341 and freely selectable API grades which are shown on the 10x4” touchscreen.
SVMTM 4001 provides an unbeatable combination of features that simplify the measurement process. Both density cells are equipped with the FillingCheck technology compliant with D4052 requirements, which allows real-time monitoring of the fi lling quality of the density cells. This saves valuable time as bubbles are already detected during the measurement.
SVMTM 4001 is designed to provide the Viscosity Index, kinematic viscosity and density of lubricating oils, base oils and additives, as well as in-service oils. In addition, the optional modular combination with Anton Paar refractometers allows for fast determination of the carbon-type composition of transformer oils with automatic calculations according to ASTM D2140 and D3238.
The SVM 3001 Stabinger Viscometer is a highly precise kinematic viscometer with an integrated density measuring cell. A single measuring cycle on a sample volume as low as 1.5 mL yields the kinematic viscosity, density, dynamic viscosity, Viscosity Index and more.
As the density cell of SVM 3001 is integrated, the density measurement according to ASTM D4052 and ISO 12185 does not have to be carried out separately. One combined measuring cell covers the entire measuring range for viscosity, density and temperature, and is fi lled in one go. SVM 3001 stands out for its unbeatable ease of operation: Simply inject the sample via syringe and start the measurement. The parameters are shown on a 10x4” touchscreen including a special intuitive precision widget, freely selectable API grades and more.
FillingCheck ensures monitoring of the fi lling quality of the density cell in real time and works for the entire viscosity range and also for opaque samples.
With unprecedented heating and cooling rates of up to 20 °C/min and a temperature range from -60 °C to +135 °C, SVM 3001 is perfectly suited for a wide range of samples and measurements. As temperatures down to -20 °C can be reached without external cooling due to its own built-in air cooling, SVM 3001 is ideal for jet fuel certifi cation according to ASTM D1655, D7566 and DEF STAN 91-91. Temperatures down to -60 °C are reached by connecting an external cooler with methanol-free cooling. SVMTM 3001 is capable of performing very fast temperature scans, so valuable information on the critical viscosity of the fuel can also be obtained in an easy and fast manner.
With the brand new SVM 2001 Stabinger Viscometer, Anton Paar expands its SVM series to provide a viscometer with the proven benefi ts of the SVM technology for a temperature range from 15 °C to 100 °C and a viscosity range from 0.2 mm2/s to 30000 mm2/s. Kinematic and dynamic viscosity are measured according to D7042 with a minimum sample volume of only 1.5 mL. Its intuitive software and unbeatable ease of operation make SVM 2001 suitable for a wide variety of measurements at any constant temperature within the range.
In order to maximise productivity and meet the demands of high throughput, all SVM™ models can be used with a 71-position sample changer.

Advantages of Using ED-XRF Spectroscopy for the At- Line Analysis of Sulphur in Fuels Is Detailed in New Application Brief
The use of energy dispersive X-ray fl uorescence (ED-XRF) spectroscopy to cut production delays from days to minutes in the at-line analysis of sulphur in fuels is discussed in a new application brief available to download from Spectro Analytical’s website.
Sulphur content is a key quality determinant for many petroleum products. A better understanding of the sulphur content in fuels impacts both production processing and assists compliance with government regulations. Traditionally, the analysis of sulphur in fuels has been performed in the laboratory using XRF spectroscopy. This practice, however, often results in production delays due to the time required to transport samples from the line to the laboratory, as well as the time samples spend waiting in queue at the lab to be processed.
Now, a new generation of portable ED-XRF spectrometers has enabled the rapid and accurate at-line analysis — right at the production line — for many applications requiring the detection of sulphur in fuels.
With portable ED-XRF spectrometry, at-line analysis can be performed from samples collected from any process point, and it fully conforms to the ASTM D4294 requirement for analysis time of 1 to 5 min per sample.
The new application brief, “At-Line Analysis of Sulphur in Fuels According to ASTM D4294 Using ED-XRF Spectroscopy”, details tests comparing laboratory and at-line analyses of sulphur in fuels and production samples. The at-line analysis was conducted using a SPECTROSCOUT portable spectrometer, which provided laboratory-level accuracy, required minimal sample preparation, excellent reliability, and showed compliance with criteria set out in ASTM D4294.
The brief also provides helpful guidance for the specifi cation and selection of an at-line ED-XRF system, including factors to consider when comparing ED-XRF spectrometers — and notes the vast differences in instrument performance, ease of use, and suitability for the at-line analysis of sulphur in fuels.
Download the new brief, “At-Line Analysis of Sulphur in Fuels According to ASTM D4294 Using ED-XRF Spectroscopy,” from the Spectro website. The brief is authored by SPECTRO Analytical Instruments, a leading global supplier of analytical instruments for optical emission and X-ray fl uorescence spectrometry.

Electronic Maintenance Indicators for Gas Filters
Restek’s electronic maintenance indicator is a monitoring device that warns you when planned maintenance for a gas fi lter is due. Simply attach it to the consumable that you would like to monitor and the device will progressively display real-time fi lter status, allowing analysts to follow a controlled replacement schedule instead of responding to “last minute” color changes from traditional indicators. Prevent unexpected downtime by controlling your routine maintenance schedule with an electronic maintenance indicator from Restek.
Electronic maintenance indicators are factory set to a 12-month interval, but can be custom confi gured by users to match their routine maintenance schedules. These devices are to be used with Super Clean®, In-Line, and Big Trap gas fi lters and come with a battery, a USB cable, and a mounting clip.
