Aijiren 7697A Headspace Sampler Operation

vials, the HS uses a single-vial oven to equilibrate the sample at the desired temperature. If configured with the 111 sample vial tray, the HS uses a 12 vial oven for equilibrating samples at temperature. Since the longest hold time in headspace analysis is typically the equilibration time, using a multi-vial oven allows the higher capacity HS to
