New Product Release: Blossmate™ PSV C18

Autumn has chilled the painted screen in candlelight; A palace maid uses a fan to catch fireflies. The steps seem steeped in water when cold grows the night; She sits to watch two stars in love meet in the skies.
Have you felt cold on the autumn night? And Who is the she in your heart? For me, she’s Blossmate™ PSV C18.

It is a dedicated column designed for the detection of food additives
Other common C18 column analysis of food additives, either dehydroacetic acid and saccharin sodium are too close, or dehydroacetic acid tailing is undesired.


BlossmateTM PSV C18 has stronger retention ability and is comparable to other C18 reversed-phase columns. The improved tailing and excellent resolution are highly appreciated.
