Thomas A. Little, PhD, is president, Thomas A. Design of experiment is a powerful development tool for method characterization and method validation. Design of experiments DOE is a well-proven characterization approach within product and process development and a key aspect of quality by design. Recently, more attention has been placed on applying DOE to analytical methods. DOE for analytical methods has three major applications: method development for new methods or those that need improvement, method validation, and quantitation of the influence of analytical methods on product and process acceptance and out-of-specification OOS rates.

HPLC Method Development and Validation for Pharmaceutical Analysis

И хотя в обычных обстоятельствах пришлось бы проверять миллионы вариантов, обнаружить личный код оказалось довольно просто: приступая к работе, криптограф первым делом вводил пароль, отпирающий терминал. Поэтому от Хейла не потребовалось вообще никаких усилий: личные коды соответствовали первым пяти ударам по клавиатуре. Какая ирония, думал он, глядя в монитор Сьюзан.

Смит поднял брови. - Выходит, выбор оружия был идеальным. Сьюзан смотрела, как Танкадо повалился на бок и, наконец, на спину.

ГЛАВА 106 К окну комнаты заседаний при кабинете директора, расположенной высоко над куполом шифровалки, прильнули три головы. От раздавшегося взрыва содрогнулся весь комплекс Агентства национальной безопасности. Лиланд Фонтейн, Чед Бринкерхофф и Мидж Милкен в безмолвном ужасе смотрели на открывшуюся их глазам картину.

Бринкерхофф застонал, сожалея, что попросил ее проверить отчет шифровалки. Он опустил глаза и посмотрел на ее протянутую руку. - Речь идет о засекреченной информации, хранящейся в личном помещении директора.

Возможно ли, что проблема шифровалки каким-то образом связана с вирусом. - Мидж… я уже говорил… - Да или нет: мог в ТРАНСТЕКСТ проникнуть вирус. Джабба шумно вздохнул. - Нет, Мидж.


 - На его компьютере уже стоял жучок! - Он говорил, стараясь, чтобы его слова были слышны между сигналами.  - Этот жучок вмонтировал кто-то другой, и я подозреваю, что по распоряжению директора Фонтейна. Я просто попал на все готовое.

Беккер осмотрел одежду. Среди вещей были паспорт, бумажник и очки, засунутые кем-то в один из ботинков. Еще здесь был вещевой мешок, который полиция взяла в отеле, где остановился этот человек. Беккер получил четкие инструкции: ни к чему не прикасаться, ничего не читать. Просто все привезти.

Шаги неумолимо приближались. В голове у него не было ни единой мысли - полная пустота. Он не знал ни где он находится, ни кто его преследует и мчался, подгоняемый инстинктом самосохранения. Он не чувствовал никакой боли - один лишь страх. Пуля ударила в кафельную плитку азульехо чуть сзади.

Как в тумане она приблизилась к бездыханному телу. Очевидно, Хейл сумел высвободиться. Провода от принтера лежали. Должно быть, я оставила беретту на диване, - подумала. Кровь, вытекающая из головы, в голубоватом свечении казалась черной.
