Micro Laboratory Aids Petroleum Research Conservation of expensive.and scarce chemical materials (some of which
may have taken months to distil in minute quantit ies); saving of two thirds in sorely needed laboratory space; and ability t o study substances so small as to defy analysis by ordinary means are advantages gained by the Gulf Oil Corp. through its micro laboratory a I Harrnarville, Pa. Quantities of solutions dealt with are somet imes so small that they must be kept in transparent, humidified cells to prevent their evaporation on exposure to air. These smaller samples, manipulated by specially designed instruments can be analysed with far greater rapidity than normal amounts .
Gulf authorities claim that the micro laboratory is making valuable con» tributions to petroleum research. Microscopic? work is being successfully applied to regulating the size of catalysts through use of microscope grid screens, and so-called dark field microscopy, wliere objects arc studied by refracted l ight, is proving successful in the application of silicones used in non foaming oil.
