Our Latest Technology & Applications
Safe and efficient Sulfur Hexafluoride Tracer Gas Testing to detect lubricating oil consumption under full engine working condition.
Having a great impact on engines’ emission, lifetime and cost of use, lubricating oil consumption is one of the most important parameters in engine development. There are four main sources of lubricating oil consumption: piston ring linear system, crankcase ventilation, turbochargers and valve stems.
Using Sulfur Hexafluoride Tracer Gas System, a full working condition lubricating oil consumption map can be obtained in 4-6 hours.
The testing system consists of hot wire pitot tube, sulfur oxidizer and ion molecular reaction mass spectrometer.
Using ion molecular reaction mass spectrometer to detect the real-time lubricating oil consumption, the system has a reproducibility ratio of more than 3%. It can detect the oil consumption of every piston ring and turbocharger. The principle is that the system calculates the engine oil consumption by detecting the sulfur concentration in the exhaust gas, taking into consideration of engine air intake, petrol consumption as well as the sulfur concentration in the lubricating oil and petrol.

SGS used FID-analyzer to measure nmHC
SGS has used the latest dual channel FID-analyzer from Testa GmbH, Germany to measure nmHC. The response time is less than 5 seconds. Unlike the traditional method which needs to switch between CH4 and THC mode during the testing, the new analyzer can measure the real-time change of nmHC concentration accurately. It is equipped with the mini solid-state hydrogen storage module from H2Planet, Italy, which gives it great flexibility in different applications.
Quick and unharmful detection of anthocyanin content in vegetables
The Vegetable Research Center of Beijing Academy of Agricultural and Forestry Sciences has introduced and implemented the digital continuous near-infrared spectroscopy test technology in the fresh-cut processing of fruits and vegetables. The technology has helped the researchers conduct quick digital tests of anthocyanin content in vegetables on the conveyor belts over several production lines. The system consists of a near-infrared spectrum based on projection grating and diode array detector manufactured by Polytec, Germany and three non-contact measuring probes and related accessories.
The latest technology for coal-fired boilers and waste incinerators to improve energy-efficiency, reduce carbon emission and promote health and safety at workplace
In the coal-fired power station, the high-resolution two-dimensional acoustic temperature measurement is used in detecting and regulating the burners and coal transition system as well as adjusting the load for the operating units. Through temperature balance adjustment, the coal consumption is reduced at the same time the tube explosion caused by coking and over-heating is avoided The core principles of the combustion and temperature balance control is to predict the temperature distribution based on the operating parameters of the burner. When the imbalance of temperature distribution is detected, the burner parameters will be adjusted to achieve the temperature balance again. The testing data will become valuable control parameters that improve the boilers’ operating efficiency and safety.
In addition to this, the acoustic temperature measurement is also used in the waste incineration. Murdike Waste Incineration Plant in Holland used the technology to control each spray gun based on the temperature distribution. This has greatly improved SNCR efficiency and achieved NOx emission lower than 60mg/m3.

AI technology for VOC testing and objective odor ranking in both parts and vehicle
Vehicle odor control is an important job of car manufacturers. For a long time, human nose has been used as a testing device. Experts were selected and trained to smell and then rank the vehicle. The results were influenced by the individual mood and health condition. It is also difficult to conduct mass testing. We have assessed the fingerprint information of all materials and parts. Using the in-depth research and algorithm mode to establish a model that is not affected by individual condition, achieving objective odor ranking.
Quick and continuous VIAQ test of parts and vehicle
The standard test to analyze the VIAQ-related components is conducted in a laboratory. Samples are collected by the researchers manually using Tenax tubes and DNPH tubes, which will be then analyzed by GC-MS and HPLC in the laboratory. The whole process is time-consuming and prone to human mistakes.
However, using an ion molecule reaction mass spectrometer with highly selective measuring features, the quantitative quantification of components required by VIAQ can be completed in a matter of minutes and is highly consistent with laboratory methods. The analyzer can be calibrated with standard materials that are easy to prepare.
Vehicle VOC long-term trend prediction
By collecting vehicle VOC emission data over a period of 15-30 minutes, the VOC level of the same vehicle in 30 days can be predicted using a tested mathematical model. This can significantly help the newly-built vehicles to demonstrate whether they have met the national standards when they are off the assembly lines by providing quick and reliable prediction.
Vehicle VOC and odor tracing
Based on the fingerprint graphics of parts and vehicle from the ion molecular reaction mass spectrometer and the respective objective odor evaluation data, it is possible to trace the parts that contribute to the emission of VOC and source of odor in the vehicle, which will make it easier to find the relevant solutions.
Parts and vehicle objective odor evaluation
Based on the fingerprint graphics provided by the ion molecular reaction mass spectrometer, through in-depth learning algorithm, it is possible to establish the correlation among VOC emission concentration, composition combination mode and odor evaluation. Through this process, the objective odor ranking can be achieved.
Hydrogen fuel cell test
AirSense and HSense provided by V&F can be used for hydrogen impurity detection and hydrogen solenoid valve control test applications. They have been hydrogen fuel cell R&D test equipment designated by companies such as by BMW.
With a response time within millisecond, the biggest advantage of V&F devices is their wide range of applications based on the soft ionization technology. Just one device can perform all the gas composition test required by ISO14687-2 :: 2012 standard.
