compact unit features all of the key components of a traditional gas chromatograph,
including an injection port, temperature and pressure controls, a thin capillary column
through which different substances pass at different rates depending on various chemical
and physical properties, and a sensor for detecting the arrival of compounds. A new patent-
ed MEMS chip sensor is also included to allow for room air to be used as a carrier gas. This
advanced MEMS chip technology allows an internal pump to push room air through as the carri-
er gas for seamless measurements. You can also connec other carrier gases to the unit. Designed
for simpleoperation, the chromatograph is easy to work with and ideal for student use. Simply connect
the device to the Vernier LabQuest or your own computer for real-time data acquisition. Using either Vernier

Motion Detector
Study the motion of a person walking, a ball in free fall, a
cart on a ramp, and much more. Using ultrasound to meas-
ure distance, the motion detector emits pulses, which are
reflected from a target, and then detected by the device.
The time it takes for the reflected pulses to return is then
used to calculate position, velocity, and acceleration. The
detector can measure objects within a range of 15 cm to 6
m. The short minimum target distance allows objects to be
closer to the detector and reduces stray reflections. A spe-
cial track mode also tailors the sensitivity for dynamics carts
on tracks for lower noise and higher quality data. The device
attaches easily to the Vernier Dynamics track and has a piv-
