17- با استفاده از کدام یک از تجهیزات زیر می توان توزیع جرمی سایز ذرات را تعیین کرد؟

 الف هزلت
ب) کاسکید ایمپکتور
چ) سیکلون
د) الوتر یاتور عمودی

کاسکید ایمپکتور: این وسیله ذرات بزرگتر را در اولین صفحه و ذرات کوچکتر را در صفحه بعدی جمع آوری می نماید.کاسکید ایمپکتور با اندازه بزرگتر برای تهیه نمونه‌های محیطی و از کاسکید ایمپکتور کوچک تر برای تهیه نمونه های فردی استفاده می گردد. صفحات ایمپکتورهای اختصاصی ممکن است تک جتی یا چندجتی باشند.ذرات جمع‌آوری شده در هر صفحه با توجه به دانسیته و اندازه ذره و قطر آیرودینامیک متفاوت است.نمونه های جمع آوری شده به کمک میکروسکوپ شمارش می شود یا وزن ذرات ته نشین شده بر روی صفحات سنجیده می‌شود و تا به روش های شیمیایی تجزیه و تعیین مقدار می گردد.

19- اندازه گیری ذرات در دستگاه پیزو بالانس بر اساس کدام یک از اصول علمی ذیل است؟

الف پراکنش نور بانفلومتر
ب)  پراکنش نور با آشکارساز مناسب 
ج) اندازه گیری پراش نور حاصل از تابش با حسگر 
د) برخورد ذرات با حسگر داخل دستگاه

 نام دیگر دستگاه پیزو بالانس دستگاه میکروبالانس کریستال کوارتزی است. این دستگاه بر اثر برخورد ذرات با حسگر داخل آن یا بر اساس رسوب ذرات بر حسگر، اندازه گیری را انجام میدهد.
