We analyzed noble gases in an oxidized residue prepared from a HF‐HCl residue of the Saratov L4 chondrite. The Ar, Kr, and Xe concentrations in the oxidized residue are two orders of magnitude lower than those in the HF‐HCl residue, and they are close to concentrations in the bulk. The He and Ne concentrations are similar in the three samples. The Ne isotopic ratios are almost purely cosmogenic, indicating absence of presolar diamonds (the carrier of the HL component). Thus, Saratov contains… 
On the carrier phase of the “planetary” noble gases: TEM, Raman, and stepped combustion data for acid‐resistant residues from the Saratov (L4) meteorite
Acid‐resistant residues (ARR) were separated from the Saratov (L4) meteorite with the aim to shed more light on the origin of the planetary noble gases (the Q‐gases) in meteorites and the nature of
Origin of isotopically light nitrogen in meteorites
Bulk meteorite samples of various chemical classes and petrologic types (mainly carbonaceous chondrites) were systematically investigated by the stepped combustion method with the simultaneous
Isotopic Composition of Noble Gases, Nitrogen, and Carbon in the Ozerki New L Chondrite
The isotopic composition of noble gases, nitrogen, and carbon in two samples of the Ozerki L chondrite, which differ in the degree of impact metamorphism, analyzed by the methods of stepwise

Noble gas study of the Saratov L4 chondrite
Abstract– We have determined the elemental abundances and the isotopic compositions of noble gases in a bulk sample and an HF/HCl residue of the Saratov (L4) chondrite using stepwise heating. The Ar,
Raman spectroscopic study of the noble gas carrier Q in the Allende meteorite
We report Raman spectroscopic results of four density-separated fractions of a floating fraction (material similar to HF-HCl residues enriched in heavy noble gases) of the Allende meteorite. The

Highly Concentrated Nebular Noble Gases in Porous Nanocarbon Separates from the Saratov (L4) Meteorite
The majority of heavy noble gases (Ar, Kr, and Xe) in primitive meteorites are stored in a poorly understood phase called Q. Although Q is thought to be carbonaceous, the full identity of the phase
Pyridine Treatment of Insoluble Organic Matter from Chondrites Krymka and Vigarano --- No Effects on the Noble Gas Carrier Phase Q
Introduction: Phase Q is the principle carrier of primordially trapped noble gases (Q-gases or P1) in primitive meteorites. It is concentrated in insoluble organic matter (IOM), oxidizable, and is
