Desenvolvimento de um detector piezelétrico para cromatógrafo a gás interfaceado a microcomputador
A piezoelectric detector based on a commercial quartz crystal of 3.57MHz is shown. A PTFE cell attached to the GC-column outlet holds the polymer-coated crystal, whose terminals were removed. Two TTL oscillators (reference and sensor) are used and the beating of their frequencies is monitored throug...
