At the end of my fermentation I want to kill the yeast any tips on how to do this without wiping out the alcohol or the taste?

You don't kill the yeast, you just use campden tablets to prevent reproduction of the yeast. That has no affect on alcohol or taste.

Would this protect new sugars from being converted to alcohol?

Campden tablets prevent new yeast, which means there are no new yeast to convert remaining sugars. It is known as stabilizing

Quote:
Campden tablets (potassium or sodium metabisulphite) are a sulphur-based product that is used primarily in wine, cider and beer making to kill certain bacteria and to inhibit the growth of most wild yeast: this product is also used to eliminate both free chlorine, and the more stable form, chloramine, from water solutions (i.e., drinking water from municipal sources). Campden tablets allow the amateur brewer to easily measure small quantities of sodium metabisulphite, so it can be used to protect against wild yeast and bacteria without affecting flavour.
Typical use is one crushed Campden tablet per gallon of must or wort. This dosage contributes 67 ppm sulfur dioxide to the wort but the level of active sulfur dioxide diminishes rapidly as it reacts with chlorine and chloramine, and with aldehydes (particularly in wine). Therefore, the concentration of free sulfur dioxide is greatly diminished by the time the beer or wine is consumed. However, when used only for the purpose of dechlorinating tap water before brewing, 1 tablet will effectively treat 20 gallons of water. Campden tablets are also used towards the end of the fermentation process to halt the ferment before all the available sugars are converted by the yeast, hence controlling the amount of residual sweetness in the final product. This balancing between sweet, dry and tart flavors is part of the artistry of wine and cider making.
Campden tablets typically weigh 0.44 g each and 10 of these are equivalent to one level teaspoon of sodium metabisulphite. (See potassium metabisulphite and sodium metabisulphite.) Other related substances are sodium/potassium sulfite/bisulphite. Further complicating the subject, each is also referred to interchangeably as --sulphites, and the 'bi' can be found as 'di'. In terms of usage, sodium thiosulphite is a closely related compound.

nukinfutz..don't you have to use sorbate with the campden? When stabilizing wine it takes both. Most beer and wine yeasts can withstand sulfites from what I understand but the addition of the sorbate with the sulfites will stop reproduction. ALSO to the OP, if you plan to bottle carb you cannot do this.

You don't have to but combining them is common practice.

I'm actually surprised the wiki (the quote I used) doesn't explain that in a little more detail, though it does make mention of it. I actually had to look it up, because I have always just used campden tabs. According to what I found, mostly from Yooper of course, they are probably best combined.
