Description
分離媒体としては、HPLCカラム、GCカラム、カラムクロマト用カラム、前処理用カラム、ガードカラム、固相用カートリッジ、パッシブサンプラー等に使用され、モノリシック吸着剤・分離剤を主体として、ガラスをクラッドとして使用する方法及び器具を提案する。
又、内径1mm以下の溶融石英チューブ内部でモノリス体を形成させたキャピラリーモノリスHPLCカラムも市販されている。
又、耐圧性を上げるために無機バインダーを含ませることもしているが、樹脂と無機バインダーにより、モノリス以外の特異的な分離挙動が生じてしまう。
又、樹脂で覆うためには樹脂軟化点以上に温度を上げる必要があり、クラッド化により化学処理部分が劣化してしまい、高性能を発揮することが出来ない。
chem,420 A(2001)、N.Tanaka etal.モノリシックカラム等に詳しく説明されている技術による。
ガラスの種類として、硬質ガラス、軟質ガラス、低融点ガラス、パイレックス、セラミクスなどがあり、SiO2が主成分ならば、軟化温度を変更すればどれでも使用できる。
温度及び圧力を0.1〜10気圧程度で調整する。方法は限定されるものではなく、モノリス体側面がガラスに均一に密着されていれば良い。
前記説明により得られたモノリスゲル2(ガラス管1の内径2.4mmi.d.より若干小さい(2.20〜2.39mmi.d.程度))をガラス管1に入れる。次に、眞空ポンプを使用し、100〜380Torrの引圧にし、温度をかける。硬質ガラスの場合は、730℃、軟質ガラスの場合は、530℃程度が良い。
更に、高圧が必要となるHPLC用に対応させるために、保護管を取り付ければ使える。
12MPa以上の耐圧性を持たせるためには、保護層を設けることが良い。ガラスクラッド化したモノリス体は、均一になっているが、一部だけに高圧がかかると破損が生じる。その側面を均一に保護層で覆うだけで、圧力は分散され、耐圧性が得られる。
次に、両端を切断し、便宜長さにし、樹脂層に接触しないようにフィルター及び接続ジョイントを取り付けることで、28MPa以上の高耐圧HPLCカラムに対応できる。
次に、両端を切断し、便宜長さにし、フィルター及び接続ジョイントを取り付ける。このように保護を行うと、60MPq以上の耐圧が得られ、高圧HPLCにも対応できる。
ジョイント7には、必要なフィルター8、テフロン(登録商標)等のパッキン9を設けるのが良い。
本発明は、ポリアクリル酸(HPAA:シグマ・アルドリッチ製 平均分子量10万ダルトン、平均重合度1390)2.4gを、1M硝酸4.0g及びホルムアミド1.0gに溶解させ、その溶液にテトラエトキシシラン6.51gを加え、10分間混合し、加水分解させた。
更に、これを裏付けるものとして、両者の境界近辺の電子顕微鏡写真6及びそのガラスコート側の視点AにおけるZAF法簡易分析によるX線分析のスペクトル図7を示す。電子顕微鏡写真6と同様の写真8におけるガラスコートとシリカモノリス体境界上の視点Bにおける簡易分析によるX線分析のスペクトル図9を示す。

顕微鏡写真を示す。
本願発明カラムでは、ピリジンはフェノールの前にシャープに溶出するが、従来カラムではピリジン、フェノールピークのテーリングが見られる。従来カラムでは、化学処理を行ったモノリス体を、樹脂でクラッド化しているため、樹脂部分は処理されておらず、高い疎水性を示すため内部と管壁近くでは、ピリジンやフェノールのような水溶性化合物ではピーク形状が悪くなったと思われる。
このように、本実施例では、725℃において最も良い結果が得られ、理想とされるガラス内面とモノリス体側面との全面同化に近い状態となっていると考えられる。
