A process for removing residual monomers from polyoxymethylene homo- or copolymers, comprising the following process steps:a) the residual monomers are removed in gaseous form as vapors from the polymer in a devolatilization apparatus,b) the residual monomer vapors are removed through a vapor pipe,c) the residual monomers are condensed from the vapors in a condensation apparatus at from 1. A scattered radiation are detected which is scattered by the object of interest under a particular predetermined scatter angle, without moving the detector array. Additionally, the drum type heat exchanger uses a drum with a short radius of rotation so that an entire operation cycle time is shortened and a heat transfer area is sufficiently secured in order to keep the thermal efficiency high. It thus exhibits a length greater than that traversed by the electrical signal, for example between a first and a second region of interaction between this control signal and this luminous flux. Because the units of execution used to run the separate VM instances are provided by the operating system, the operating system is able to ensure that the appropriate degree of insulation exists between the VM instances. Analysis cassettes, systems of analysis cassettes, supplemental modules, and methods for producing analysis cassettes are also described.
