The most exacting needs of laboratories throughout the world are most eminently and successfully met by Vitreosil ware (pure fused silica) produced to the high est standards of quality. Chemical purity, high re sistance to heat shock, un usual electrical resistivity, best ultra-violet transmis sion (in transparent quali ty) and low initial cost com pared to platinum are some features of Vitreosil fused quartz. In addition to our unusually large stock of transparent and opaque, including glazed and unglazed cruci bles, evaporating d i s h e s , beakers, tubing and rods in all diameters and sizes, we offer prompt fabrication of special items.

and product development stages must be adapted to regular routine testing. This is particularly true when the chemical is a completely new product. Final Product Approval. The Ana lytical Division establishes that all products shipped from the plant com ply with existing specifications. Analytical Division Organization
Figure 2 outlines the organizational arrangement of the Analytical Division at a refinery where a number of Oronite's chemicals are manu factured, and illustrates the organiza tional arrangement used at our various plants. It is a sizable division, occupying a separate building and employing over 200 people, handling approximately 5000 tests per day. The analytical groups within the division serve both the chemical and oil manufacturing operations. The differences in the analytical require ments of the chemical and petroleum industries are adequately accommo dated by the integration into the divi sion of technical people specially trained in each field. Such integra tion enhances the division's technical efficiency and permits the utilization of the best in analytical equipment which might not be justified for a single field. Process and quality control efforts are always geared to the requirements for attaining high quality consistently, whether the product be sold in terms of pounds or thousands of barrels.

Responsibilities of Analytical Groups
The responsibilities of the various sections within the Analytical Division may be outlined as follows : Methods Section. The supervisor of the Methods Section is responsible
for the analytical methods used by all groups. His personnel develop new analytical techniques and adapt those reported in the literature to the com pany's needs. In addition, the group works closely with the California Research Corp. in developing new techniques on new products or proc esses. Analytical Section. This group handles laboratory examinations which are unusual—i.e., not routine. A good example is the actual sulfonation of Alkane as the final acceptance test for the product prior to detergent manufacture. Chemical Section. The Chemical Section has the responsibility for all chemical analysis not covered by the analytical group. A specific example given in Figure 3 is the bromine number tests for propylene polymer in Alkane manufacture. Physical Section. This group handles all physical analytical tests. Examples are specific gravity and dis tillation. General Section. The General Sec tion personnel are those involved in the nontesting operations of any laboratory. The washing of glass ware is a part of their responsibility. Figure 3 shows the Analytical Divi sion and its relation to the manu facture of a typical Oronite product, Detergent D-40, including partial list of tests carried out. Following this product through from raw material to finished state shows how the various sections of the Analytical Division are involved in relation to a manufactur ing operation. General Functions
