We report highly reproducible gravimetric and optical measurements of microdroplets that lend insights into the fundamentals of drop-on-demand (DOD) printing. Baseline fluidic pressure within the DOD dispenser was controlled to within 0.02 hPa, enabling long-term stability in dispensed droplet mass
Postmortem changes of thinner components in body tissues were examined in rats, orally given 1 ml of standard thinner solution, which was prepared by mixing toluene, ethyl acetate and isobutanol in the proportion of 8:1:1. Analysis was made by gas chromatography combined with the head space method.
