SAPHIR-PLUS-PLUS

SAPHIR-PLUS-PLUS

The atmospheric simulation chamber SAPHIR-PLUS-PLUS enhances the experimental possibilities at the SAPHIR chamber. SAPHIR-PLUS-PLUS is based on the principle of a constantly stirred tank reactor (CSTR) and is based on the successful concept of the JPAC chamber (selected publications: Mentel et al. (2009, 2013, 2015), Kiendler-Scharr et al (2009) ,Ehn et al. (2012, 2014), Wildt et al. (2014), Sarrafzadeh et al. (2016)). An average residence time of the air in the chamber is achieved by a chamber volume of 2 m³ and a constant flow of 30 liters per minute. The supply of high purity air is realized either via the SAPHIR synthetic air supply or with purified ambient air. The use of different artificial light sources enables the selective control of single photo-chemical reactions. The SPAHIR-PLUS-PLUS chamber is housed in a specially constructed climate chamber to allow for precise regulation of the air temperature. SAPHIR-PLUS-PLUS offers ideal conditions for mechanistic studies of both formation of secondary organic aerosol as well as the atmospheric gas phase chemistry. The SAPHIR-PLUS-PLUS chamber is currently under construction and will be ready to use by end of 2018.
