  We present a study S K-edge using high-resolution HETGS {\it Chandra} spectra
of 36 low-mas X-ray binaries. For each source, we have estimated column
densities for {\rm S}~{\sc i}, {\rm S}~{\sc ii}, {\rm S}~{\sc iii}, {\rm
S}~{\sc xiv}, {\rm S}~{\sc xv} and {\rm S}~{\sc xvi} ionic species, which trace
the neutral, warm and hot phases of the Galactic interstellar medium. We also
estimated column densities for a sample of interstellar dust analogs. We
measured their distribution as a function of Galactic latitude, longitude, and
distances to the sources. While the cold-warm column densities tend to decrease
with the Galactic latitude, we found no correlation with distances or Galactic
longitude. This is the first detailed analysis of the sulfur K-edge absorption
due to ISM using high-resolution X-ray spectra.
