The sample was removed before reaching the ignition temperature then cooled to room temperature in a desiccator
. The volatile matter was calculated as the percentage weight loss.
Japanese standards state the limit values by the desiccator
method with 4 levels of formaldehyde limit, including the average and the maximum value.
5,b shows the parameters of the insulating gaps in the initial state and after a two-week exposure (336 hours) in the desiccator
. The capacitances of the gaps have increased little, but tg[delta]a has grown significantly more, and to a greater extent for wires distant from each other (the region of small partial capacitances, the left part of Fig.
The samples were then stored in desiccators
with their respective salt solutions at every relative humidity value.
Methanol was added to the resulting crude material and the insoluble solid was filtered off, washed with cold methanol and dried in a desiccator
. Analysis of the NMR spectra and X-ray structure of the isolated material revealed that the obtained product possessed the structure of 2,2'-(1,3-diphenylpropane-1,2-diylidene)bis(hydrazinecarboximidamide) dihydrochloride 4a.
Sample was dried in the oven at 90 - 100degC, cooled, grind, sieved (1 mm) and stored in the desiccator
After whole congelation, we put the test film specimens on the surface of congealed mixture and placed Petri dishes into a desiccator
, in the bottom of which distilled water is poured.
A valuable technique in the dermatologist's clinic, it can treat small skin tags, several of which can be removed in one treatment session without any anaesthesia, using a fine metal electric desiccator
This experiment was carried out in a sealed glass desiccator
(30 cm (diameter) and 30 cm (height)).
The extremely low relative humidity ([+ or -] 10%RH) storage condition was set up in desiccator
using saturated salt, lithium chloride as described by Greenspan .
After 24 hours, 40 ml water was added and a white material was obtained which was dried under desiccator
and in vacuum.
The resulting potassium salt of ethyl xanthate was dried in a vacuum desiccator
over anhydrous calcium chloride.
The technique was not using CPD for drying process but it was only by air-drying in desiccator
Samples were stored for 24 h, and then transferred to a desiccator
at 37 [+ or -] 1[degrees]C.
The purpose of this part of the study was to determine the weight loss behaviour of hemp fibres when kept in a desiccator
and when exposed to elevated temperature and thus to determine the equilibrium moisture content of the fibres.
