Abstract: A new toilet aid apparatus has a positioning aid configured to be adjusted and positioned on the toilet seat to adjust the effective size of the toilet seat, and a securing mechanism configured to secure the adjustable back support to a toilet and thereby fix the effective size of the toilet seat. The positioning aid may support the back of a user seated on a toilet seat and may be easily removed or moved out of the way for users not needing the positioning aid.

Abstract: A metallic sample block has formed therein a serpentine shaped duct containing glass beads. The block is secured in thermally conductive contact with a thermoelectric element to which voltage of one polarity is applied to chill the block to a range of approximately -25.degree. C. to -90.degree. C. When the block temperature has been lowered sufficiently a gas sample is conveyed in one direction through the duct causing contaminates therein to be condensed out on the beads. Thereafter the polarity of the voltage applied to the thermoelectric element is reversed to cause it to heat the block and vaporize the previously condensed contaminates, after which a carrier gas is conveyed in the opposite direction through the duct to a gas analyzer device.
