20 Real-time Drop Analysis for Inkjet Printing


In April, Krüss will unveil its new Drop Shape Analyzer – DSA Inkjet, a measuring instrument for analysing the properties and flight behaviour of ink drops after exiting the print head. During ink development and quality assurance, the interaction between the print head control and the ink must therefore be perfectly adjusted and monitored. The DSA Inkjet was specifically designed for this task. With its integrated printer electronics, it communicates directly with the print head installed in the instrument and analyses the ink drops in real time.


Once the print head has been inserted into the instrument in a just few simple steps, the intuitive waveform editor realistically simulates the electronic control in a printing process. The microscopic lens depicts the drop beam in a sharp and high-contrast manner. The DSA Inkjet uses an imaginative method to precisely analyse ink drops of just a few picolitres at flight speeds of up to 40 m/s: two different-coloured light flashes in swift succession provide double exposure of the drop in a single colour camera video image. By separating the colour channels, discrete images of the same drop are obtained at intervals of a few milliseconds.


The software-controlled measurement provides mean values for the drop’s volume and speed, trajectory (deviation from the vertical), length of the ligament and number of possible unwanted satellite drops. The data is generated as immediate feedback on the dynamically adjustable print parameters and is particularly suitable for checking an ink or optimising the printing process. Easy-to-create automation programs also enable measurements under repeatable conditions to test ink formulations in a standardised manner.


A separate lens observes the nozzles from below to make unwanted ink drops visible on the rows of nozzles. Another innovative development makes it easier to measure real drop dimensions such as volume or ligament length. The image scale is automatically determined with the aid of a calibration grid regularly projected into the camera image.


Inserting the print head and focusing on individual nozzles is a matter of a few simple steps thanks to the 3D fine positioning. The instrument is also equipped with a storage tank to supply the print head with ink during long-term measurements, whereby the drops are collected in a waste container. A suction device prevents harmful vapours. Thanks to a UV protection cover, UV-curing inks such as those used for 3D printing can also be examined.

New Compact Gas Analyser Family Introduced


Hiden Analytical introduces the new HPR-20 range of application-specific compact benchtop gas analysers for dynamic measurement of in-process gas composition. All systems feature precision quadrupole mass spectrometers with standard mass range options 200 and 300 amu, with mass range options from 20 to 1000 amu being available for specialised applications.


The HPR-20 EGA system is configured for fast-response evolved gas measurement at near-atmospheric pressures utilising bypass capillary sampling, with sample consumption rates typically 1-15 mL/minute. Systems are routinely used in conjunction with thermal gravimetric analysers (TGAs), with standard interface options available for operation with a wide range of TGA systems.


The HPR-20 TMS Transient system offers the optimum response time for fast event studies. The system uses a direct pulse ion counting detector with a 7-decade dynamic range, from 1 to 107 counts per second, and with the multichannel scalar option provides a time resolution of just 50 nanoseconds. The TMS system uses the 3F-series quadrupole with triple-stage mass filter providing optimum abundance sensitivity for mass resolution of minor species.


The HPR-20 R&D system is optimised for the researcher, with a wide selection of standard and customised system interface configurations available including options for direct sampling from sample pressures up to 30 bar. An 8-channel multi-stream selector option enables sample auto-selection from multiple gas streams, and a 4 or 8-channel mass flow-controlled gas preparation module provides on-line precision gas mixtures for system calibration and for direct supply to the user’s reaction process.
