Is the Sarin Claim Bogus?
From an alert reader: ( Disclaimer: I know nothing about chemistry. ed. )
(Be sure to read the last 'graph, if only to hear about the Lousiest Job in the World.)
Shorter version: this device, an Iraqi binary weapon, probably didn't have sarin in it at all, and the alerts were to cyclohexanol. Why?
1. bc the insurgent deployed the weapon as an HE round, thereby showing he didn't know what it was.
2. bc Iraqi binary weapons require the use to POUR IN THE SECOND INGREDIENT BY HAND AT THE LAST MINUTE.
Therefore, if there had been sarin, that would have required a level of care belied by the device's use, according to Gen. Kimmett. And if the shell was deployed as if it were an HE round, no sarin could have been present. Another false positive. Stratfor's coverage not only missed this, it also missed simple facts in the Kimmett account!

During its war with Iran, Iraq initiated the use of chemical weapons, beginning with sulfur mustard in 1983, progressing to tabun in 1984, and then to sarin (and eventually VX) beginning in 1987. Sarin was also used in attacks on Iraqi civilians, most notably in the March, 1988 destruction of the Halabja, where civilian deaths caused by a cocktail of different agents have been estimated at 5000.
Iraq mass produced sarin during the Iran-Iraq war with the expectation that it would be used quickly, and they therefore skipped several purification steps. Fresh agent was about 60% pure and heavily contaminated with hydrogen fluoride (which, of course, also causes health problems in exposed individuals). When production caught up with demand, the Iraqis started storing their sarin in refrigerated "igloos" to prolong its storage life. However, even when stored in the igloos, the material rapidly degraded, becoming less than 10% pure within 2 years.
This was one of the factors that lead the Iraqis to investigate binary weapons, for which sarin is particularly well suited. While they had not mastered the art of manufacturing binary munitions in which the mixing of the precursors occured on firing at the time of the invasion of Kuwait, they had developed a simple process for generating the agent immediately before use: a warhead or shell would be given a partial fill of isopropanal (and often cyclohexanol, a precursor for the related nerve agent GF, sometimes known as cyclosarin) and stored along with plastic containers of methylphosphonic difluoride (DF). Shortly before the munition was to be used an Iraqi soldier would be provided with a gas mask and would pour an appropriate amount of the DF into the munition. This eliminated storage issues.
