Coupling capillary electrophoresis to mass spectrometers through the Agilent triple tube coaxial sheath-fl ow sprayer is a widely used confi guration due to its simplicity, versatility, and robustness. This Technical Overview shows that with the Jet Stream source and the latest version of the CE/MS sprayer, this approach can now also be used in combination with the proprietary Agilent Jet Strea...

The effective quantification of deposition rate is vital importance in optimizing the application performance and utilization pesticides; meanwhile, canopies fruit tree orchards are large, with dense branches leaves shading each other, making it difficult to quantify spraying efficiency. Therefore, imperative develop a facile methodology for assessing different techniques terms distribution orc...

Potato is a national superior vegetable commodity that prioritized for development by the government. Bener Meriah Regency center potato development, supported climatic conditions suitable growth. However, so far production of plants has not been able to meet Indonesia's domestic needs. This study aims describe what technologies are applied farmers in and want see how level technology adoption ...

The article presents research results of a machine-tractor unit that performs two technological operations simultaneously: (i) chopping plant residues (sunflower stubble); (ii) covering the chopped stubble with soil. first operation is carried out front-mounted chopper, and second one rear-mounted plough. chopper’s working devices are rotated by tractor’s front power take-off (PTO), which has o...

A new, more robust sprayer for desorption electrospray ionization (DESI) mass spectrometry imaging is presented. The main source of variability in DESI is thought to be the uncontrolled variability of various geometric parameters of the sprayer, primarily the position of the solvent capillary, or more specifically, its positioning within the gas capillary or nozzle. If the solvent capillary is ...

for a determination of soil characteristics one should have access to instruments that can measure these characteristics, including: soil penetration resistance with high accuracy. one of the accurate instruments commonly employed in soil penetration determinations is cone penetrometer. this apparatus, by measuring soil cone index at different soil depths can provide useful about information ab...

The flow of air generated by a new design of air assisted sprayer equipped with two axial fans of reversed rotation was analyzed. For this goal, a 3D sonic anemometer has been used (accuracy: 1.5%; measurement range: 0 to 45 m/s). The study was divided into a static test and a dynamic test. During the static test, the air velocity in the working vicinity of the sprayer was measured considering ...
