ANNOUNCING the first truly automatic and uncomplicated w a y to accurately quantitate your chromatograms... the N e w VARIAN CDS-101 It's the only d a t a system that will accurately quantitate gas or liquid c h r o m a t o g r a m s completely on its o w n . Y o u d o n ' t have to run a n d m a n u a l l y m e a s u r e trial c h r o m a t o g r a m s or get p u n c h y p u n c h i n g in sets of p r e - r u n i n s t r u c t i o n s .

Y o u just turn it o n . Inject y o u r s a m p l e . A n d c o m e b a c k later to get a c o m p l e t e report on the w h o l e c h r o m a t o g r a m .

A n d the 101 's a u t o m a t i c b a s e l i n e c o r r e c t i o n assures a c c u r a t e m e a s u r e m e n t of all peaks w h e t h e r the b a s e l i n e is d r i f t i n g or stable. M u l t i p l e - t a n g e n t peaks and c o m p l e x - f u s e d peaks are a c c u r a t e l y resolved and the entire true area of e a c h p e a k is integrated — all a u t o m a t i c a l l y .

It's that s i m p l e b e c a u s e the C D S - 1 0 1 a l r e a d y k n o w s w h a t to d o . All the critical peak m e a s u r i n g p a r a m e t e r s have been p r e s e t at o p t i m u m values to a c c u r a t e l y quantitate m o s t c h r o m a t o g r a m s . Of c o u r s e , y o u c a n a l w a y s o v e r r i d e the preset p a r a m e t e r s a n d reset t h e m at w h a t e v e r values y o u m i g h t n e e d to p r o c e s s u n u s u a l chromatograms. T h e C D S - 1 0 1 is also the o n l y c h r o m a t o g r a p h y data system that automatically adapts itself to changing analytical conditions so that each p e a k in your c h r o m a t o g r a m is d e t e c t e d and m e a s u r e d in the most a c c u r a t e way. At the b e g i n n i n g of an a n a l y s i s the 101 a u t o m a t i c a l l y selects the most sensitive setting that will reject n o i s e a n d a c c u r a t e l y m e a s u r e the first peak. T h e n , after e a c h peak, as the a n a l y s i s c o n t i n u e s , the 101 a u t o m a t i c a l l y u p d a t e s its peak m e a s u r i n g p a r a m e t e r s to k e e p t h e m c o n s i s t e n t w i t h s u c h

B e c a u s e the C D S - 1 0 1 does more automatically on the inside, everything about it is less c o m p l i c a t e d on the outside. T h e c o n t r o l s are m u c h s i m p l e r a n d easier to use. A n d the s i m p l e interactive interface with all c h r o m a t o g r a p h s a n d with a u t o m a t i c s a m p l e r s , v a l v i n g , t e l e t y p e w r i t e r s , a n d other d e v i c e s , gives y o u greater c o n v e n i e n c e a n d system versatility. T h e C D S - 1 0 1 will a u t o m a t i c a l l y m a k e y o u r lab life a w h o l e lot easier. A n d m o r e p r o d u c t i v e .
