LDC doesn't b u i l d the best general purpose laboratory spectrophotometer, but we ao make the best variable wavelength monitor for HPLC! The s p e c t r o M o n i t o r I has been totally engineered to w o r k w i t h your c o l u m n for m a x i m u m resolution and efficiency. It has the lowest noise level w i t h a full 10 m m pathlength cell and a w i d e range of wavelengths that permit y o u to measure your c o m p o u n d at its m a x i m u m absorbance level — t o give you ultimate measurement sensitivity. T w o source lamps that cover the full 200-700 n m range are built-in so you w o n ' t have t o physically change lamps. Just switch-select the lamp for the wavelength range you want. A 10 μΙ cell v o l u m e , fast response t i m e , and zero dead v o l u m e fittings make the s p e c t r o M o n i t o r l ideal for high speed, high resolution, high performance LC. Everything about the s p e c t r o M o n i t o r ' s design makes it perfect for HPLC because making LC monitors is our specialty.
LDC offers a fast g r o w i n g line of monitors, recorders, pumps, columns, valves, fittings...everything under the sun for liquid chromatography! Call or write for detailed i n f o r m a t i o n on our c o m p l e t e p r o d u c t line today. A n d watch for c o n t i n u i n g additions to the LDC family of liquid chromatography products. The s p e c t r o M o n i t o r I is just one of many!
