developed an in-line on-line instrument that continuously removes moisture from wet steam and monitors the moisture (quality) content of the steam.  In hospitals, when steam is supplied from a central source it is often what is termed "dirty steam". This refers to the quality (% moisture) and purity of the steam and indicates that the steam contains too much moisture, chemicals, salts, and other undesirable elements/compounds.  This is the cause of various sterilization problems including:</div> <div> <IMG BORDER="0" SRC="Symb075c00b700c800000000.gif" HEIGHT="13" WIDTH="24" ALIGN="bottom" HSPACE="0" VSPACE="0">Insufficient or slow sterilization</div> <div> <IMG BORDER="0" SRC="Symb075c00b700c800000000.gif" HEIGHT="13" WIDTH="24" ALIGN="bottom" HSPACE="0" VSPACE="0">Shortened life span of the autoclave due to the corrosivity of the steam</div> <div> <IMG BORDER="0" SRC="Symb075c00b700c800000000.gif" HEIGHT="13" WIDTH="24" ALIGN="bottom" HSPACE="0" VSPACE="0">Shortened life of expensive stainless steel and gold instruments</div> <div> This leaflet presents a description of the Jonas, Inc.
