FAQ
Q1: So wobetumi de quartz dɔn toa no adi dwuma ne hydrofluoric acid (HF)?
A1: Dabi HF ne SiO2 yɛ adwuma ma ɛyɛ silicon tetrafluoride (SiF4), na ɛde ɔsɛe a wontumi nsakra ba. Fa PTFE anaa fluoroplastic chambers di dwuma ma HF-a ɛwɔ akwan horow.
Q2: So wobetumi asɔ quartz dɔn toa no ano wɔ vacuum a ɛkorɔn ase?
A2: Yiw, sɛ wɔde gaskets a ɛne no hyia (sɛ nhwɛso no, kɔbere ma ultra-high vacuum, Viton ma low/medium vacuum) ne flanges (ISO-CF ma 10−10 mbar, ISO-KF ma 10−6 mbar) bom a. Hwɛ sɛ mmeae a wɔde nsɔano no ho tew na ɛnyɛ nsensanee.
Q3: So quartz ade no siw UV hann ano?
A3: Dabi-quartz de UV hann kɔ fam kodu 200nm, na ɛma ɛyɛ nea eye ma UV-sensitive applications. Wɔ UV-blocking ahiadeɛ ho no, quartz a wɔakata so titire anaa nneɛma foforɔ wɔ hɔ (di yɛn ho nkɔmmɔ na woanya ano aduru a wɔahyɛ da ayɛ).
Q4: So metumi atu ntokuru anaasɛ mede hyɛn gyinabea ahorow ahyɛ quartz dɔn toa no mu?
A4: Yiw, denam mfiri a ɛyɛ pɛpɛɛpɛ a yɛn adwumayɛbea no yɛ so. Kyerɛ hyɛn gyinabea akɛse, mmeae, ne ahorow (gas a ɛkɔ mu, anyinam ahoɔden a wɔde fa mu, viewport) bere a woreyɛ no sɛnea wopɛ na ama woahwɛ ahu sɛ ɔdan no yɛ pɛpɛɛpɛ na mframa ntumi nkɔ mu.
