Fingerprinting: HP 8400A Spectrometer

HP’s 8400A microwave spectrometer could help scientists determine the molecular structure of a substance by using microwaves to trace that substance’s “fingerprint.” Before its advent, scientists had to assemble their spectrometers themselves, which could lead to problems with performance. Hewlett-Packard’s device was shipped ready-to-go and backed by the company’s impeccable reputation for reliability. It was introduced with a price of about $45,000.
