Measurements Solutions for Additive Manufactured Parts
Additive manufacturing (AM) is a relatively new and growing technique which is complimentary to more conventional, subtractive methods like machining. The major advantage of AM is that it allows the manufacturing of complex geometries and the creation of internal features that cannot be easily produced using subtractive methods. One major disadvantage of AM, however, is the reduced control of surface quality and dimensional ...

Measurements Solutions for Optical Material Homogeneity
An important property of an optical component is the variation of the refractive index of the material from which it is made, broadly referred to as homogeneity. Material inhomogeneity causes variation of the refractive index in a glass, which can be in the form of sharp, cord-like regions called striae or it can occur as a gradient of the refractive index through a larger region of the sample. Material index variations must be qualified to ensure their impact is within tolerance for a particular optical design ...

Continuous emissions monitoring for sulphuric acid production plants
The process control of a sulphuric acid plant needs good and reliable detection of gas phase sulphur dioxide (SO2). To measure SO2 is a challenge due to the corrosive environment and high concentration of SO2. Several places in the process needs to be monitored and to transport the sample gas is difficult. A large dynamic range is needed as the SO2 concentration can vary between 15% volume and a few mg/m3. Most systems installed need a lot of maintenance, sometimes as often as every ...

Continuous emissions monitoring solutions for H2S monitoring
To monitor H2S can be difficult. The UV absorption is without structure and the IR absorption has strong interference from H2O. The traditional way has been to remove all SO2 from the sample while keeping H2S, then convert H2S to SO2 ,and finally measure SO2 which then effectively yields the H2S concentration. The instruments used have often been ambient air SO2 analysers and extractive dilution systems. However, it is not unusual to experience practical problems with these type of ...
