Standard building blocks give the nexo P-E Model 18U-B Process Vapor Fractometer the flexibility of the most advanced special engineering developments in process gas chromatography. A new, highly versatile instrument, the. Model 184-B brings automatic process control by gas chromatography within the reach of virtually any petroleum or chemical processing plant.

The Model 184-B uses building block sampling and sensing units in various combinations to produce process analytical systems which mean continuing extra dividends through reduced maintenance, low-cost training and highest reliability.

These standard building blocks include multi-port

sampling valves for backflushing and analyzing heavy ends . . . versatile multi-column systems . . . multi-stream programmer kits . . . pneumatic units for automatic control.... and a wide variety of sampling devices.

Perkin-Elmer, the world's largest manufacturer of gas chromatographic instruments, will help you in your process instrumentation requirements. For more information, write for a new descriptive booklet.

All building blocks hi any P-E system, conform to standard -refinery and chemical plant safety practices.
