Validation of an environmental exposure unit for controlled human inhalation studies with grass pollen in patients with seasonal allergic rhinitis.
Norbert Krug,H. Loedding,Jens M. Hohlfeld,M. Larbig,A. Buckendahl,Philipp Badorrek,H. Geldmacher,W. Behnke,Wilhelm Dunkhorst,Horst Windt,Birgit Luettig,Wolfgang Koch +11 more
TL;DR: There is an increasing need for allergen inhalation systems to perform basic clinical research and test anti‐allergic drugs under well‐controlled conditions, which requires stability of environmental conditions like temperature and humidity, as well as allergenic concentration and reproducible induction of allergic symptoms.

Ultrafine particles at workplaces of a primary aluminium smelter
Yngvar Thomassen,Wolfgang Koch,Wilhelm Dunkhorst,Dag G. Ellingsen,Nils-Petter Skaugset,Lars Jordbekken,Per Arne Drabløs,Stephan Weinbruch +7 more
TL;DR: The study shows the existence of elevated number concentrations of ultrafine particles in both potrooms and the main source of these particles is likely to be the process of anode changing.

- 01 Jul 1992
TL;DR: A condensation nucleus counter has a humidifier zone, through which the sle air is guided, and an approximately perpendicularly arranged condensation zone, as well as an optical detection system with a light source and detector as mentioned in this paper.

Evaluation of the Respicon® as a personal inhalable sampler in industrial environments
Wolfgang Koch,Wilhelm Dunkhorst,Hubert Lödding,Yngvar Thomassen,Nils Petter Skaugset,Alexander Nikanov,James H. Vincent +6 more
TL;DR: The Respicon as mentioned in this paper is a personal sampler for health related measurements of airborne contaminants at workplaces, which is aimed at simultaneous collection of three health related aerosol fractions: (a) the coarser inhalable fraction, defined the aerosol fraction that may enter the nose and mouth during breathing; (b) the intermediate thoracic fraction, defining the fraction that might penetrate beyond the larynx and so reach the lung; and (c) the finer respirable fraction, which may penetrate to gas exchange region of the lung.

A sampler for total suspended particulates with size resolution and high sampling efficiency for large particles
TL;DR: In this article, a Wide Range Aerosol Classifier (WRAC) was used to compare the performance of various widely used dust samplers for a field intercomparison.
