Experimental and computer studies of plasma created in initially evacuated polyacethal and polyethylene capillaries are reported.Soft X-ray spectroscopy is as a capillary plasma diagnostic tool.The measured time integrated spectra foe polyacethal and polyethylene capillaries correspond properly to the spectra resulting from the computer simulations using NPINCH and FLY codes.
