Could somebody help: What means boxcar? Is it a process or system, or???boxcars samples
Boxcar - Sets the number of 40 Hz detector samples that are averaged for slope detection. Refer to the section on Chromatographic features. The specified value is a power of 2; i.e. power = 4 results in 16 samples per boxcar average. Each boxcar event should be followed by a slope event

multidimensional chromatography: The use of two or more columns or chromatographic techniques which enable a better separation. It is useful for sample cleanup, increased resolution, and increased throughput. It can be used off- line by collecting fractions and reinjecting onto a second column or on- line by the use of a switching valve. It also called coupled column chromatography, column switching, multicolumn chromatography, or boxcar chromatography. HPLC Glossary, Waters Corp., 2003
