Chemist Barry Francis loads Brazilian soil samples into an autosampler for mid-infrared analysis of carbon content. Helvecio De-Polli is not an (ARS) scientist, but a casual observer wouldn't have known that. For 2 years, he participated in a research collaboration, known as LABEX, between ARS...

...of. Figure 9 shows a common method to drive an LED. The carrier frequency is 40 kHz, which equates to 24. Because infrared LEDs typically require current on the. pulses during a zero’s high time (600 μs) and 48 pulses. order of 50-100 mA, driving the LED directly from the. during a one’s high time (1.2 ms...

...fixed-filter mid-infrared analyzer with. no moving parts and an insignificant optical air path. It weigh less than 5 pounds and can be. operated from a battery pack or a cigarette lighter adapter cable. This makes it portable, sturdy and. operable in a range of ambient conditions typically found in field...
