A pipe handling system is designed for use on an offshore structure, particularly an offshore structure provided with a cantilevered drill floor. A beam of pulsed radiation is directed onto a portion of the sample to desorb analyte molecules. The common generic interface provides support for overflow detection when a result of an operation being performed on a particular numeric type will result in an overflow situation when the operation does not fit within a range supported by the particular numeric types. The heating chamber warms the metal in the chute, and material in the chute can be exposed to exhaust gas, which preheats the asphalt material.
