TWO INSTRUMENTS FOR VINYL CHLORIDE IN AMBIENT AIR PORTABLE ANALYZER The MIRAN l1** Portable Analyzer is an ideal instrument for the determination of vinyl chloride concentrations quickly and accurately over a range of from <1 ppm to several thousand ppm. It easily can be carried to work areas, process plants, or shipping and receiving platforms -- wherever vinyl chloride is made or used -- for on-site profiling of vapor levels. Sensitivity. <1 ppm vinyl chloride Response Time: <1 minute Weight: <30 pounds Method: Infrared, variable wavelength CONTINUOUS MONITOR European Cfiorhjea! gev.'s, jQne jtg, tgy, Italian survey predicts European PVC prospects \ recent survey of world PVC markets by Alessandro Rollo, Carrara, Italy con cludes growth rates will stabilize at around 10 per cent annually, after reaching an average of 14 per cent in the 1968-72 period. With Japan and the USA unable to meet rising demand from the developing countries over the next 10 years, western Europe is expected to maintain its dominance of world PVC markets. Urging that European PVC investment be maintained despite the energy crisis, the survey predicts that western Europe wilt have PVC capacity of around 6-Sm. ton/year by 1980, with real production at about 6m, ton/year. European consumption will total around 5-8tn. ton by 1980, concludes the survey, leaving only 200000 ton/ year for export demand, expected to be around three times as much by 1980, at close to 600 000 ton /year.

The MIRAN IITM Continuous Monitor records vinyl chloride levels at up to 12 sample stations on an unattended around-theclock basis and includes provision for overlimit alarms.
