" . . . a constant delivery rate of 0.843 μ\ per minute" T h e University o f N o r t h Carolina recently developed a unique application f o r a Hamilton Gas T i g h t Syringe w h i c h p e r m i t s t h e use of t h e f r o n t a l t e c h n i q u e in gas-liquid c h r o m a t o g r a p h y T h e syringe is used in conjunction w i t h a s y n c h r o n o u s m o t o r and linear s c r e w , t o introduce a liquid s a m p l e a t a c o n s t a n t rate into a m o v i n g gas s t r e a m . T h e 2 r p m m o t o r t u r n s a precision lead s c r e w (52 t h r e a d s / i n c h ) w h i c h drives t h e plunger of t h e 5 0 μΙ syringe resulting in a c o n s t a n t delivery rate o f 0 . 8 4 3 μΙ per m i n u t e . T h i s corresponds t o approximately one d r o p per hour» In science and industry, as well as education, research people have discovered t h a t t h e y can d e p e n d on Hamilton f o r precision measuring equipment.
