Daily activities, such as for example walking up a short air travel of stairs or carrying a suitcase, can become very difficult as the problem gradually worsens.Thirty-five % lighter than its predecessor, the 4300 FTIR offers the performance, mobility, flexibility and user comfort nothing you’ve seen prior attained in a handheld FTIR device. We believe this handheld FTIR is certainly a game-changer for the cellular FTIR field, said Phil Binns, Agilent's vice president and managing director of Spectroscopy. It’s not only portable and compact, but its advanced ergonomics make the machine comfortable to make use of for extended periods of time, leading to better-quality data. Users is now able to get rapid, field-based analyses without any sample preparation, reducing the right time to actionable outcomes.
