range—
W i t h the analyst's growing interest in t h e near-infrared region of t h e spectrum, it is significant that the Beckman D K Spectro photometer has been selected as the standard in producing near-infrared curves. T h e near-infrared region, from .7 to 3.5 microns, is proving valuable in many fields, and especially in rocket fuel investigations. In fuming nitric acid for example, detection and measurement of water content is critical because the presence of 1 % water sharply cuts burning efficiency. Beckman D K - 1 a n d D K - 2 are fully auto matic recording instruments. With operating versatility and a broad line of accessories for h u n d r e d s of research a n d quality control applications, they offer the widest wavelength range—185 mM to 3500 mM (.185 μ to 3.5M) — taking full advantage of ultraviolet and visible regions plus the important near-infrared.
