Dr. Phil Williams
Phil Williams ทำงานที่สถาบันวิจัยการเกษตร (Agricultural Research Institute) นิวเซาท์เวลล์ ประเทศแคนาดา โดยทำงานกับนักวิจัยปรับปรุงพันธุ์ข้าวสาลีเป็นเวลาหลายปี ในเดือนกุมภาพันธ์ 1970 เขาได้รับมอบหมายงานใหญ่ในการคัดแยกข้าวสาลี hard red spring โดยใช้ปริมาณโปรตีน เขาต้องคัดแยกข้าวสาลีปริมาณทั้งสิ้น 20 ล้านตันต่อปี โดยใช้รถไฟขนลากรถรางทั้งสิ้น 300,000 คันต่อปี ที่จุดรับ Thunder Bay และ Vancouver ปริมาณข้าวสาลีขนาดนี้ ทำให้ Canadian Grain Commission เสียค่าใช้จ่ายสูงมากสำหรับสารเคมี 47 ตัน ในการทดสอบ 620,000 macro-Kjeldahl test ในปี 1972-73 สามารถตรวจสอบได้ 480 ตัวอย่างต่อ 7 ชั่วโมงในหนึ่งวัน ด้วยกำลังคน 5 คน (4คน ตรวจสอบ 1 คน บดตัวอย่าง) Phil เริ่มกังวลใจ และหาวิธีการอื่นในการตรวจสอบ ในปี 1971 เขาได้ทราบข้อมูลว่ามีเครื่องมือที่สามารถทดสอบโปรตีนได้โดยใช้เวลาเพียง 10 วินาที ด้วยความแม่นยำ 0.1% จากนั้นผู้อำนวยการสถาบันได้อนุมัติให้ซื้อเครื่อง NIR จากบริษัท Neotec (NIRsystems ในปัจจุบัน) ด้วยเงิน 7,200 ดอลล่าร์สหรัฐ เครื่อง NIR เครื่องแรกของแคนาดานี้ ได้มาถึงห้องปฏิบัติการของ Phil ในวันที่ 3 กุมภาพันธ์ 1972 การทดสอบ NIR ได้เริ่มต้นครั้งแรก เครื่องมือทำงานได้ไม่ดีนักแต่ดีพอที่ทำให้ Phil ได้เชื่อมั่นว่า การใช้ NIR ในการวิเคราะห์โปรตีนเป็นทางที่ถูกต้อง Phil เข้าใจถึงความสำคัญของการสร้างสมการทำนายก่อนการใช้เครื่องมือ เขาใช้เวลาหลายปีในการค้นพบและปรับปรุงสมการทำนายเพื่อลดความผิดพลาดในการทำนาย การสุ่มและการเตรียมตัวอย่าง ความไวของสเปคตรัมต่ออุณหภูมิ และความชื้น ในเดือน พฤศจิกายน 1973 Phil ได้เสนอสมการทำนายโปรตีนและความชื้นในข้าวสาลี บาร์เล่ย์ และโอ๊ต ในการประชุมทางวิชาการที่จัดโดย AACC ประเทศสหรัฐอเมริกา ในปีต่อมา Phil ร่วมกับบริษัท Neotec ได้ริเริ่มระบบการวิเคราะห์อัตโนมัติ (Automated Digital Analyser; ADA) ขึ้นโดยทำงานร่วมกับเครื่อง NIR โดยมีระบบการวัดสเปคตรัมตัวอย่างอัตโนมัติ ซึ่งควบคุมโดยคอมพิวเตอร์ ระบบนี้ได้เริ่มใช้ตรวจสอบโปรตีนอย่างจริงจังในปี 1976 เป็นผลทำให้ห้องปฏิบัติการวิเคราะห์โปรตีนด้วยวิธี Kjeldahl ใน Calgary ปิดลงอย่างถาวรในปี 1976 นอกจากนี้ Phil ได้ใช้เวลาหนึ่งปีศึกษากับ Karl Norris ผู้ซึ่งเป็นบิดาแห่งวงการ NIR ที่ Beltsville ในปี 1977 เขาทั้งสองได้พัฒนาวิธีการปรับปรุงสเปคตรัมทางคณิตศาสตร์ (Mathematical treatment) เพื่อชดเชยความผิดพลาดในการทำนายโปรตีนเนื่องจากการแปรปรวนของขนาดอนุภาค และความชื้น Phil ยังได้เสนอแนวคิด ร่วมกับ Wally Zarowsky เกี่ยวกับการชดเชยความแปรปรวนอุณหภูมิ โดยวิธีการสร้างสมการทำนายชดเชยอุณหภูมิ ซึ่งถือเป็นตัวอย่าง Chemometrics ในยุคต้น ของวงการ NIR
ในปัจจุบัน Phil Williams มีอายุ 73 ปี และยังทำงานเป็นที่ปรึกษาให้กับบริษัทหลายบริษัทในหลายประเทศ ในด้านการตรวจสอบคุณภาพสินค้าด้วยเทคนิค NIR และผลงานของท่านในขณะนี้ยังดำเนินการจัดการกับข้อมูลจำนวนมากๆเพื่อสร้างเครือข่าย (Networking) ให้เชื่อมโยงกับสถานีตรวจสอบหรือโรงงานหลายๆโรงงานที่มีเครื่อง NIR หลายๆตัว โดยการควบคุมจากแล็ปกลาง (a central laboratory) ด้วยเครื่อง computer ตัวเดียวซึ่งเป็นระบบที่ทันสมัยเหมาะสำหรับอุตสาหกรรมอาหารสัตว์, อุตสาหกรรมน้ำตาล, อุตสาหกรรมเมล็ดพันธุ์พืช และปรับปรุงพันธุ์ เป็นต้น ท่านมีผลงานที่ได้รับความสำเร็จทั้งในออสเตรเรียและในแคนาดาได้รับเชิญให้ไปบรรยายพิเศษและเป็นอาจารย์ในหลายประเทศรวมทั้งผลงานที่ได้รับการตีพิมพ์เผยแพร่ตลอดจนการเขียนหนังสือ (text books) อยู่หลายเล่มและที่สำคัญท่านได้รับรางวัลอันทรงเกียรติหลายรางวัล (ตามเอกสาร CV ของ Phil Williams)
